Cyanobacteria - KNO3
I have an 18 gallon tank with no CO2 and one T5 bulb. I only have three or four stems in there with some amanos, crs, and tetras.
I've been reading up on my latest tank problem and apparently I need to keep some KNO3 on hand. My nitrates test low (5.0) and is probably the cause of cyanobacteria. I read the sticky and it's undergoing a black out right now.
My questions is how much and what quantity should I invest in some KNO3 and where is the best place to find it? My LFS told me to try a place that sells pond stuff... I think I rather just order it online.
They also told me to take out my plants. Should I?
