This sums up the difference of scrubber-tanks vs. skimmer-tanks, when it comes to corals.I feed em like crazy!!! I love it!!! I would say feed those corals of yours like crazy too!! The algae is made to soak up the bad stuff so let the algae do its job. Push the feed for a coupe weeks and see what your corals look like then. I was so scared to feed mine to much for fear of nutrients building up a killing them but, just the opposite happened. I feed a ton more and the nutrients are lower then ever and they look SO MUCH better. Now I have a lot more time on my hands because of no water changes that the little cleaning of the glass does not bother me. I have found that if I scrap it with a razor it stays cleaner longer. Someone suggested that here and it works. Do as I did, jump off the deep end and feed!!!!
Scrubbers removes nutrients, and leave food in the water.I feed a ton more and the nutrients are lower then ever
Multiply your feeding by 5. You have to at least try it.I simply cannot get any growth, bar on the scrubber
You mean the one that was set up for the experiment, and which was given no time for the bacteria/microbes to grow and do their natural filtering/consumption? Reef studies show that the turnover time of bacteria requires about 3 weeks; this means that any increase in doc requires about three weeks before the bacteria/microbes can catch up with it. Just like cycling rocks requires time.The tank that did not utilise granular activated filtration or a skimmer had doc levels of 5ppm, almost five times natural levels.
DOC did not "cause" anything. Otherwise, there would never have been reefs in the first place. Guess what?... Fat "causes" heart problems. So if you have any "fat" at all, which we do, you and the rest of us are going to start having heart problem tomorrow. Yes tomorrow. It must happen, because fat "causes" heart problems. Wait a minute, you mean there are people with fat who don't have these heart problems? How? The definition is: Fat causes heart problems. Period. And, DOC "causes" coral mortality. So, using your own definition, all corals on all reefs (which all have doc) are all going to start dying tomorrow.Santa is denying outright that on reefs excess doc is a major contributor to coral mortality despite all the evidence to the contrary
Correct; it can't. That's why people dose it.DOC is food so how can it stay very high for a long period of time?
More than that. Here is one study; there are many others:DOC's in the ocean have been measured in some areas of reef up to almost 5ppm

"Carbon is the link between the inorganic environment, and the living organisms. The carbon cycle basically illustrates the interchange of carbon between the atmosphere, hydrosphere, biosphere and the lithosphere. The focus of this study is the dissolved organic carbon (DOC) in natural waters, specifically marine and estuarine waters. In natural waters, the total organic carbon (TOC) is composed of particulate organic carbon (POC) and DOC. In most of these waters, the concentration of DOC is greater than the concentration of POC. For example, in the sea, the concentration of DOC surpasses POC by a factor of 50 to 100 percent.
DOC in natural waters is usually made up of fatty acids, carbohydrates, amino acids, hydrocarbons, hydrophilic acids, fulvic acids, humic acids, viruses and clay-humic-metal complexes.
In oceanic waters, DOC levels vary around 0.5 mg/L, but can also be as high as 20 mg/L in coastal waters, and at the continental shelf.
The total DOC in seawater is [estimated at] 0.7 mg C/L, and is a major reservoir of organic carbon. In coastal waters, because of increased phytoplankton activity and the input from land, DOC values can be as high as 20 mg/L.
The production of DOC is led by the phytoplankton, via exudation and
cell lysis. The role of phytoplankton in DOC production is also important in other natural water bodies like lakes, where such release is of ecological significance because the DOC released provides a source of energy to heterotrophic consumers and decomposers. The release of DOC by phytoplankton is also considered to be a functional response of individual cells to changes in environmental conditions. In addition to phytoplankton, planktonic grazers like copepods and protist grazers also contribute to DOC production via excretion. Other marine organisms also excrete DOC via their wastes, and the decomposition of their dead bodies by microorganisms like bacteria and fungi.
Carbohydrates are highly reactive, and they support heterotrophic metabolism.
DOC plays an important role in the bio-geochemistry of any aquatic system, because it is a component of the total carbon which is cycled through organisms, the water body, sediments and plants. Therefore the bulk analysis of water for DOC is essential for the overall understanding of the production-decomposition cycle, and the variability of DOC in an aquatic system.
The tissue of all plants and animals in the marine and estuarine waters have significant amounts of carbon. The carbon is taken primarily in the dissolved state [DOC] by the organisms. In other words, DOC in aquatic ecosystems provides energy and carbon for the metabolism of heterotrophic bacteria, plus some species of phytoplankton which can subsist heterotrophically on dissolved organics.
DOC, primarily in the form of humic and fulvic acids, binds organic pollutants such as phthalates and pesticides as in the case of heavy metals.
The ultimate fate of DOC in an aquatic system is its oxidation (to carbon dioxide) by bacteria, fungi, protozoan and animals present in water. "
