My tank is currently going through a GHA crash. Instead of growing thick and bushy it is starting to get thin and long and spread throughout my tank. I'm doing all the stuff you said but I'm using seachem zooplankton instead of phytoplankton.IMO, it is generally easier and most successful to reduce GHA with herbivores (especially fish) than by nutrient control.
If one does want to try to reduce nutrients (or a trace element) to the point where GHA is limited in growth, you may need to ensure the corals in the tank are getting adequate nutrition in other ways than absorption of inorganic nutrients, such as dosing phytoplankton, organic carbon dosing to increase bacterial levels, dosing amino acids, dosing particulate coral foods, etc.
It is also important to use rocks that are already coated with bacteria or coralline algae to reduce places for algae to attach.
I guess you still have calcareous rock that "consumes" (stores) some of the dosed phosphate.Hmm wonder if I should even continue down this path. I run barebottom and have to dose phosphate
This discussion is precisely about the Wild, Wild West of bacteria. Now we have detailed information on how some of the players perform. Considering crosstalk between bacteria in surface film of corals and in the interior biomass resulting in bacteria adjusting environmental conditions thru gene expression.a raise in nutrients is what causes micro algae’s to create the film algae that we are so familiar, adjusting those depleted nutrients will have different effects, for example in your silica article you were able to change from green to brown film by just making the silica nutrient more available. With Carbon is fairly similar at the end of the day is a replacement of the end user organism or a way to redirect nutrient to allow more desirable organisms to colonise surfaces, the film will still be on the glass is just more translucent and not visible to the naked eye giving a idea that the glass is clean. Similar to silica being a depleted nutrient to allow diatoms to thrive carbon is a limiting nutrient for heterotrophic bacteria and same as with silica one can increase or decrease those films with the abundance or depletion of key nutrients.
in relation to carbon being a risk of desirable organism to suffer is minimal if done correctly, desirable organisms will not suffer as long as there is a residual of nitrates and phosphates in a system. The risk of dinoflagellates only exists if nitrates and phosphates are fully depleted or if the carbon source is suddenly stopped, imo the mistake that folks often do wend depleting a system from nitrates or phosphates using dissolved organic carbon is the sudden stop of DOC dosing, it would be more safe to raise the depleted nutrient via dosing Vs stop adding DOC.
in addition corals (often the most desirable organisms) are mixotrophs and can get energy from preying on bacteria, zooxanthellae (autotrophic) will only be at risk if nitrates or phosphates become depleted.

The first Avatar movie illustrates the connectivity of Mother Earth. While I believe in Intelligent Design, the science of Nature is quite complex. We are only beginning to understand the coral holibiont.
Recently, on the science channel, I watched German scientist demonstrate how fungus at root tips of trees supplied carbon to a struggling tree. The tree roots were in common ground as in a forest. On the surface, each tree was sealed in a seperate glass canopy dome. One dome was feed carbon 13 and one dome was feed carbon 14. When carbon 14 dome lighting was reduced by 50%, carbon 13 molecules migrated to carbon 14 dome. By reversing the lighting by reducing lighting intensity in dome 13 and raising intensity in dome 14, carbon 14 molecules migrated to dome 13.
THIS IS A CONTRADICTION to “survival of the fittest” proposed by Darwin in his book “Orgin of the Species”,

“On the Origin of Species (or, more completely, On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life),[3]published on 24 November
1859, is a work of scientific literature by Charles Darwin that is considered to be the foundation of evolutionary biology.[4] Darwin's book introduced
Taking things one step deeper into the micro world of sub atomic particle science, scientist could not explain gravity until the discovery of the Higgs Boson Particle:
After a 40 year search, a subatomic particle with the expected properties was discovered in 2012 by the ATLAS and CMSexperiments at the Large Hadron Collider (LHC) at CERN near Geneva, Switzerland. The new particle was subsequently confirmed to match the expected properties of a Higgs boson. Physicists from two of the three teams, Peter Higgs and François Englert, were awarded the Nobel Prize in Physics in 2013 for their theoretical predictions. Although Higgs's name has come to be associated with this theory, several researchers between about 1960 and 1972 independently developed different parts of it.”Higgs boson - Wikipedia

In the mainstream media, the Higgs boson is sometimes called the "God particle" after the 1993 book The God Particle by Nobel Laureate Leon Lederman,[14] although the nickname has been criticised by many physicists.[15][16]

You don't own the term rip clean. And I seen one of your rip cleans fail the other day so I'm not sure why you keep acting like this thread is harming you in some way.A problem I see here is delayed compounding. This thread extracts nothing, it only adds to. I claim that's the formula for old tank syndrome for the masses, not that your tank subsea is going to see it soon. Your tank subsea isn't the masses tanks it's an outlier among public reefs and this thread isn't about fixing invasions its about biofloc for coral feeding.
The title of this thread is misleading and should be changed and relies on key wording to get readers that wasn't earned.
This non rip clean thread is an excellent study in advanced coral feeding
Don't oversell topical kills of cyano: chemi clean can do that too
This compounding from advising all entrants to leave all waste in the sandbeds has an eventual price, and it'll keep my actual rip clean threads busy, just give em some time to express based on tank gallonage. They will have thick well- fed corals but the reef itself will display old tank syndrome, eutrophication, as unexported reefs eventually do for the masses.
I fully advocate using this for cost doser after a rip clean but never in place of one - that's forgetting the long game.
The only thread that exists for correcting old tank syndrome in other people's reefs shows its done via export, not dosers and additions. We just completed another job yesterday with pics and updated the thread.
I'm working a new job in chat today, results will be posted soon.
Thanks Hans-Werner, hope you are well.Yes, Reef Actif is more than 15 years old now. I have to say I found the main ingredient by a screening. At that time (2007) there was a hype about some additives most of which where simply mineral particles (clay, clinoptilolith, a zeolith, etc.) which may have some effect, most likely due to adsorption.
I looked for something that may have a similar effect and tried different minerals and organic substances that may show the same or a similar effect. With most minerals in my eyes the results were very disappointing, I saw no effect. But with one of the organic substances I had a lot more polyp extension of Acropora and other corals in just a few days. I also saw a significantly better growth of the basal discs of Acropora which other users also described. Other users that were more fish centered reported "improved" behavior of fish with more mating behavior. With time I added some other biopolymers that improved or at least did not lessen effect and may address more bacteria species.
I did a lot of research on google scholar and bought some books and found no 100 % explanation until today. For sure it is a bacterial thing, it is repeatably positive, and due to the nature of the biopolymers it is a kind of prebiotic effect.
I learned a lot about bacteria mobilizing nutrients since then and I also learned to read and understand behavior of corals better, especially in relation to nutrients. There are probiotic phosphate solubilising bacteria in the genus Rhizobium. Rhizobium-like bacteria are known as diazotrophs (nitrogen fixers) in coral reefs and as symbiotic diazotrophs of the coral holobiont. I am sure it is in this direction, I think mainly the phosphate solubilisation. The brighter colors of corals strongly point in this direction. It is sometimes suspected as being a copper effect but no copper is added and no elevated copper concentrations are found in the water. Brighter coral colors are most likely the result of better phosphate availability and improved coral growth. This shifts the coral colors away from deep colors with high nitrogen to bright colors with improved phosphate availability and tipping the balance away from nitrogen.
Finally, there is no way to observe it directly but I want to make trials which may show the phosphate solubilising property of bacteria grown on Reef Actif.
Effects observed in fish could be due to general prebiotic effects or due to binding of ammonium and lowering free ammonium concentrations in the water. Also in fish phosphate solubilisation and improved availability of phosphate may have positive effects.

@Tony ThompsonIts a pity Charles is not on this forum, I think he may dispute the attribution of the statement ("survival of the fittest) to himself.
A considerably large number of links to publications, articles and thesis on this thread. Far to many for me to read and disseminate as to whether specific or mutual to the concept proposed. Surprised to see a link and citation to "The Origin of Species" on a reef aquarium forum.
I think I have read enough, time to get back to Reef Notes Vol 1 (Julian Sprung) 1988. Its amazing how the wheel turns in this hobby, the same concepts keep revolving only under different titles.
On positive note you may see a jump in sales of Tropic Marin® Reef Actif
@Tony Thompson
I see the thread as positive in that newbies should realize there is science & art to reef keeping and technology & gadgets will not solve bad hysbandry. I don’t see this as a marketing sales thread. Tools are good but they don’t replace knowledge & discernment.
PS: Not so sure Darwin was insulted by my taking poetic license with his THEORIES.
Tony,I just texted Charles, but got no reply, he is probably in the pub with Joseph DH. Tuesdays is their darts night.
Tony,
I should drink a Guinness with you some time. Thank you for humor & wisdom.
I would much prefer to drink a real Yorkshire Bitter here in the "sceptered isle"While not directed at me I will say that the only way to drink Guinness is in a pub on the Emerald Isle. And not the one in NC
It just isn't the same sadly. Then again maybe I'm biased.
