Please log in for more thread options Since I have deep sand bed in my 58g reef tank I suffer
brownish-red cyanobacteria blooms...
Attempts to put green macroalgae in the sump failed.
Algae gets lighter and lighter, loosing its green color
and disapears...
All the time I measure undetectable nitrates.
Chemical methods to absorb abundant phosphates
do not work very well (use PhosAr).
What would happened if I add some ammonium nitrate
or sodium/calcium nitrate to the tank water to rise
nitrates to - let's say - 1-2mg/l and put some
green macroalgae in the lighted sump again?
Will they work as good phosphate absorbents and
provide nice food addition for my tang to eat?
Will they outcompete cyano or will I get awfull
GHA on my live rocks? :-)
