Avançado Aquário de artigos de recursos para dezembro de 2013: Alimentação Coral: Uma Visão Geral http://www.advancedaquarist.com/2013/12/aafeature ------------------------------------------------------------------------------- Advanced Aquarist Feature Article for December 2013: Coral Feeding: An Overview http://www.advancedaquarist.com/2013/12/aafeature The picture in the article shows that in the 1000 litre test tank: 98% of the food particles go to the skimmer when there are 2 coral colonies 71% of the food particles go to the skimmer when there are 40 coral colonies 92% of the food particles go to the skimmer when there are 2 coral colonies, when skimming is cut in half 55% of the food particles go to the skimmer when there are 40 coral colonies, when skimming is cut in half "This trade-off between food availability and water quality can be circumvented by using plankton-saving filtration systems, which include [...] algal turf scrubbers" "Corals are able to feed on a wide range of particulate organic matter, which includes live organisms and their residues and excrements (detritus)." "...bacteria [...] can be a major source of nitrogen." "...when dry fish feeds or phytoplankton cultures are added to an aquarium, a part of this quickly ends up in the collection cup of the skimmer. "...mechanical filters (which can include biofilters and sand filters) result in a significant waste of food." "Detritus is a collective term for organic particles that arise from faeces, leftover food and decaying organisms. Detrital matter is common on coral reefs and in the aquarium, and slowly settles on the bottom as sediment. This sediment contains bacteria, protozoa, microscopic invertebrates, microalgae and organic material. These sedimentary sources can all serve as coral nutrients when suspended, especially for species growing in turbid waters. Experiments have revealed that many scleractinian corals can ingest and assimilate detritus which is trapped in coral mucus. Although stony corals may ingest detritus when it is available, several gorgonians have been found to primarily feed on suspended detritus." "Dissolved organic matter (DOM) is an important food source for many corals. [...] scleractinian corals take up dissolved glucose from the water. More ecologically relevant, corals can also absorb amino acids and urea from the seawater" -NP

Flow phosphate rock Many people, when you get your washer racing for the first time, I worry more when algae (not least) begins to grow in its rocks. It seems very strange, especially when nitrate and phosphate were lower than before. What is happening is that phosphate is coming out of the rocks. Remember, phosphate is invisible, so you can only see the effects of it, and always "flows" at higher concentrations to lower concentrations (as heat does). Example: If your room is warm, and you put an object on the cold ground, heat from the air in the room will "flow" to the object to the object and the air are the same temperature. Example 2: If you put a hot object on the ground, the heat will "flow" of the object and go to the air in the room, once again, until the air and the object are the same temperature. Now suppose you open the windows (in winter). The hot air in your room goes out the window, and it will stay cooler in the room. The object in the ground is now hotter than the air, therefore, heat will flow from the object and the air, and then out of the window. Think of phosphate as heat, and its rocks as the object, and its windows as the purifier. As the purifier phosphate pulls out of the water, the level of phosphate in the water droplets. Now, since the level of phosphate in water is lower than the level of the phosphate rock phosphate flows of stones in water, and then from the water in the purifier. This continues until the levels of phosphate in the rocks and water are level again. And remember, you can not see this invisible stream. This flow causes an interesting thing happens. As emerges from phosphate rocks, which then becomes available to feed the algae as soon as it reaches the surface of the phosphate rock where no light. Thus, since the surface of the rocks is rough and has light, it begins to grow more algae there (no less) as the phosphate out of the rocks. That's an amazing thing to see, first, because if you did not know what was happening, you would probably think that the algae scrubber was leaking and attaching to their rocks. Here are the signals coming out of phosphate rocks: 1. Rocks are older, and slowly developed algae problems in the past year. 2. Purifier is new, maybe just a few months old, and recently started to grow well. 3. Nitrate and phosphate measurements in water are low, usually the lowest they have been in a long time. 4. Hair (not brown) green algae on the rocks increased in certain spots, usually on the corners and ridges on top. 5. The glass has no need for cleaning both. Since skimmers, filter socks, etc. do not remove any nitrate and phosphate, and waterchanges and macro fuge not pull in a lot, most people have never seen the effects of large amounts of phosphate rocks coming out soon. But surely it does. How long does it continue? For 2 months to a year depending on the amount of phosphate is on the rocks, how strong your purifier is, and how many other phosphate removal filters you have (GFO, carbon dosage, etc..) But one day you will see white rock fragments that were covered in green hair the day before; this is a clear sign that algae are losing their supply of phosphate rocks and can no longer hold signal. Now it's just a matter of days before the rocks are clear. --------------------------------------------- ENGLISH ---- ----------------------------------------- Flow out of Phosphate Rocks Many people, When They Get Their scrubber running for the first team, get worried When more (not less) algae starts to grow on Their rocks. It seems really strange, Especially When nitrate and phosphate have gone lower than before. What is happening is que phosphate is coming out of the rocks. Remember, phosphate is invisible, so you can only see the effects of it, and it always "flows" from higher to lower Concentrations Concentrations (just like heat does). Example: If your room is warm, and you put a cold object on the floor, heat from the air in the room will "flow" into the object until the object and the air temperature are the same. Example 2: If you put a hot object on the floor, heat will "flow" out of the object and go into the air in the room, again, until the air and the object are the same temperature. Now suppose you open your windows (in the winter). The warm air in your will go out room the windows, and it will get colder in the room. The object on the floor is now warmer than the air, so heat flow out of the object into the air and will, and then out the window. Think of phosphate to the heat, and your rocks to the object, and your windows to the scrubber. As the scrubber phosphate pulls out of the water, the phosphate level in the water drops. Now, since the phosphate level in the water is lower than the phosphate level in the rocks, phosphate flows from the rocks into the water, and then from the water into the scrubber. This continues until the phosphate levels in the rocks and water are level again. And remember, you can not see this invisible flow. This flow causes an interesting thing happens. As the phosphate comes out of the rocks, then it passe available to feed algae as soon as the phosphate Reaches the surface of the rocks where there is light. So, since the surface of the rocks is rough and has light, it starts growing algae there MORE (not less) to the phosphate comes out of the rocks. This is a pretty amazing thing to see for the first team, because if you did not know what was happening you would probably think the que algae in the scrubber was leaking out and attaching to your rocks. Here are the signs of phosphate coming out of the rocks: 1. The rocks are older, and have slowly developed algae problems in the past year. 2. The scrubber is new, maybe only a few months old, and has recently started to grow well. 3. Nitrate and phosphate measurements in the water are low, usually the lowest They have been in a long time. 4. Green hair algae (not brown) on the rocks has Increased in Certain spots, usually on corners and protrusions at the top. 5. The glass has not needed the cleaning much. Since skimmers, filter socks, etc. do not remove any nitrate and phosphate, and waterchanges and macro's in a fuge do not remove much, most people have never seen the effects of large Amounts of phosphate coming out of the rocks quickly. But sure enough, it does. How long does it keep? For 2 months to a year, depending on how much phosphate is in the rocks, how strong is your scrubber, and how many other phosphate-removing filters you have (GFO, carbon dosing, etc.). But one day you will see patches of white rock que were covered in green hair the day before; this is a sure sign que the algae are losing Their phosphate supply from the rocks and can no longer hold on. Now it's just a matter of days before the rocks are clear.

Ainda mais colheitas de água salgada: Even more harvests from saltwater:

Primeiros 13 dias de crescimento em um purificador de superfície flutuante. Este usou quatro LEDs de 3 watts cada, 660nm (vermelho), mas você também pode usar uma lâmpada CFL ... First 13 days of growth in a floating surface scrubber. This one used four LEDs of 3 watts each, 660nm (red), but you could also use a CFL bulb...

Como construir um purificador de superfície flutuante -------------------------- How to build a floating surface scrubber:

Se alguém está esperando para construir uma cachoeira ou de fluxo ascendente purificador, em breve estaremos postando os planos do novo purificador de superfície flutuante. Ele flutua no topo e não precisa de uma cachoeira, e ele não brilha através do vidro. -------------------------------------------- If anyone has been waiting to build a waterfall or upflow scrubber, we will soon be posting plans of the new floating surface scrubber. It floats at the top and does not need a waterfall, and it does not shine through the glass.

1982: The original dump-bucket style algae scrubber (works, but very hard to build, install, operate, and harvest) 2008: Waterfall style algae scrubber (works good but hard to build and install; must be removed to harvest) 2011: Upflow style scrubber (work goods, easier to build and install on the glass; must be removed to harvest) 2013: ??? (work great, all 3D growth, easy to build, and instant in-place harvesting without needing to remove anything or turn anything off).

Some success stories of people who built upflow algae scrubbers... ReeferMat on the MASC site: "So I decided to build one of these [uAS scrubbers] today. It's huge because all I had was a 12 inch airstone, but I'm hoping that won't matter too much. It cost me less than $20 to build, so if it works that is the best for the buck I have ever seen in the war on algae! It has been up and running for 3 months now and I have to say my tank looks a lot better. Every time I clean it it grows a new type of algae, slime, turf, etc... and it grows fast. I would say I have seen a decline in nuisance algae in my tank, but to be honest that would be an understatement.... It has all but eradicated it. Every time I look at the scrubber I can't but think that all that junk would be growing in my DT" Owenreefin on the PNWMAS site: "The first two months of running this UAS scrubber thing I was convinced I was going to rip it out for the algae growth was dismal, and I figured that my system just couldn't make it work. (I also have algae in my fuge) WELL I WAS WRONG. The thing started to really kick in. So much so that I just conducted my only water change in 2 months and I hardly think it was even necessary. I usually do a change of 30% every 2 weeks. My sand bed has cleared up big time too. With the water change I pulled out a good baseball sized amount of algae off the scrubber, couldn't be happier! I will always be running one of these. I will post pics of its growth next time I change water. Many months from now. " Bobba on the scrubber site: "Well, it's been almost 3 weeks with the HOG.5, and 2 with my lone Turbo snail. I am happy to report that I have no Hair Algae left in the tank. No signs of any regrowth of what the snail has eaten either." Clavius on the scrubber site: "I've been running a 500 liter tank now for 5 years. It is very well stocked with SPS, LPS, softies, filter feeders and a modest amount of fish. The nutrients were being kept very low by a combination of a giant skimmer and the ZEOvit method. Off course, this results in very lightly coloured corals, which was my goal. Generally I'm very pleased with the colouring and growth of my corals, and please with my tank in general. But one battle I've always lost: brown algae covering my sandbed. I could not, for the life of me, find what was causing those algae. Not to mention solve it. I've tried many many things to solve it, but up untill recently, without luck. Almost three weeks ago though, I installed a HOG.5 unit. It was a little experiment that I wanted to do ever since I learned about algae scrubbers. I was never creative enough to build one myself, as the space in my 100 ltr sump is very limited. The HOG.5 was affordable and tiny enough to enable my experiment. I could even fit 6 of those units in there with ease. Off course, with the ZEO-method, my nutrients already were really very low. I couldn't measure any NO3 or PO4 with my Salifert test kits. And I never bothered with more expensive kits; unmeasurable should be good enough. I wanted to see if the vitamins and amino acids that the algae scrubber produces would add anything to my reef. And, more importantly, if the algae would consume "something" that the brown algae on my sandbed require. The result in my sandbed is staggering. After only 3 weeks, not a trace of the pesky brown algae is left! An extra benefit, that I didn't expect, is that my lightly coloured corals now all have noticably much more colour. Without getting darker. They seem to glow! I don't know if it is from the vitamins that are released in the water [from the algae scrubber]. Or maybe the ugly brown algae [on the sand] were also covering my corals and that I now finally seeing my uncovered corals! Strangely enough, the algae in my HOG.5 aren't light green, as you would expect with nutrient-poor tanks. But they're a mix of dark brown with red tints here and there. So, I have no idea why that is or how that works. But at this stage I'm just so happy that I really don't care."

This is the Collector UAS Scrubber.
