Is ammonium chloride the only product that you dosing? And also important is are your nutrients detectable now? The effect on the nuisance will depend of several factors normally only the beneficial bacteria gets affected by some sort of limitations, dosing ammonia doesn’t automatically redirect it to the dinoflagellates
For nitrogen, I dose a mixture of calcium nitrate and ammonium chloride. My nutrients has been detectable before, during and after my episode of dino outbreak. baseline nitrate is 2ppm (+-1ppm) and phosphate of 0.02 (+-0.01ppm). During outbreak, I dose to increase nitrate to 5ppm.
Im not versed in how ozone or hydrogen peroxide oxidise ammonia unfortunately, it will depend greatly on the results of the reaction, they should aid in the reduction of blooms as any other product depending on the chemical reaction. I know bacteria is effective as they can process ammonia into nitrates that are much harder for this species to assimilate in comparison to ammonia.
although is interesting that algae starts growing once you stop the carbon dosing this will mean that once heterotrophic bacteria becomes limited in DOC to grow and divide nitrifying autotrophic bacteria can’t pick up the slack instantly allowing algae to assimilate the ammonia instead.
This may be true in some aquarium. It could just as likely that other (desirable) organisms rapidly utilize these available nutrients.
I wouldn't. In fact I would probably increase the dosage as coral grows. For a simple reason, these nitrogen is well utilised by my corals and clams. The reason to incorporate ammonium chloride is that ammonium is easier for corals to use.
Absolutely, in a mature system we will have plenty of good photosynthetic organism growing all over the system that could easily pick up the slack from the extra ammonia, on a fairly new system that contains the dinoflagellates cell and just clean rocks the outcome is guaranteed to bloom, folks often disregard that biodiversity is not just bacteria, there is many beneficial organisms that cover the rocks including coraline algae that will be beneficial in this situations.
That's deeper in the woods than I venture. My best guess being that algae being always present become top predators when left to their own. Saw this with FW tests when enough plants were added to out compete single cell algae as well as GHA. They disappeared. Could be same with autotrophs as you mentioned or could be that algae are tasking advantage of the excess nitrates not being removed by heterotrophs. I tend to believe the latter.with all the dissolved organic carbon you mentioned that you dose it doesn’t surprise me that ammonia is not something you fear
Saw that mentioned the other day and makes sense. Might be that dosing nitrates was going in the correct direction but not far enough of a start. Nitrogen being the need and ammonium being the best source to get everything started plus plants and other photosynthetic organisms tend to prefer ammonium otherwise having to down convert nitrates to it.
The same happens in reefing, it’s fairly common to add algae beds to outcompete GHA, often with a stronger lighting that the DT will be enough to redirect the nutrients from GHA to a more desirable algae that will assimilate ammonia through photosynthesis
The bacteria in the media is still functional just not at his full potential, it will need time to adjust to the new levels of ammonia. This is due to the heterotrophic bacteria that was being stimulated for growth and division by etanol or acetic acid becomes limited by reducing the dose or stop dosing. The gap between the ammonia that was being oxidised by heterotrophic bacteria and the time that it takes for the nitrifying bacteria to grow and divide will be were the system becomes more susceptible at allowing nuisance to develop if present in the system, a way to reduce this risk is by dosing carbohydrates to the system following stoping the acetic acid or ethanol this that will give the nitrifying autotrophic bacteria a source of carbon to stimulate a rapid growth not allowing ammonia levels to raise.
Familiar with algal turf scrubbers or refugiums and what lead me to test this in FW but how do you dose carbs? Not following you on why autotrophs need carbon. My understanding, that's purely a heterotroph need and detritus often forms that source which could contain carbs along with other nutrients based on composition.
I know how it may sound although carbohydrates are a natural occurrence in the sea, normally from decomposing sea weed or phytoplankton. Small boost from this carbon source is mimicking the sea in a way.
That's news to me and good to learn something new daily. Thanks
I believe the triton method advocated for this, if I’m not wrong in the Refugium method.
