It has been used before for fw, but I can find little in the sw world. Can I just muse a little here, then use this thread to pull all the info together?
Based on the Redfield ratio (), fw aquarists add nitrogen compounds to rid their systems of algae. They manipulate levels of nitrogen compounds to make the conditions good for vascular plants and hard for algae to grow. Could we use this principle in sw, to encourage the algae to grow?
The ratiionale behind this: By manipulating the nitrate levels in our tanks, we can drive down the level of phosphate.
Has anyone heard this already? I have experimented with it a lot over the past few years, and it has worked every time. I can let the PO4 level go up, then add nitrate and the po4 comes down. PO4 absorbers are expensive, difficult (and stinky) to recharge, and can cause drastic shifts in the PO4 levels. By manipulating the nitrate levels, we can keep the level of po4 low with just a routine addition of a nitrogen compound.
Only works with tanks with algae, of course. Algae scrubbers, refugiums or symbiotic algae in corals.
Anyone seen anything published around lately, dealing with this theory?
