I'm hoping someone here can help me out. I've been battling GHA for a while, doing all the recommended things, manual removal, reducing lighting time, controlled feeding, adding herbivorous fish, inverts/cuc etc. My nitrates consistently read 0.0 on the Hanna checker and confirmed with Salifert. Phosphates are consistently at .05-.07. I'm worried about dinos taking hold. I'm assuming that my nitrates are reading zero because it's being sucked up by the GHA. My question is this....Should I dose nitrates to get those up in an effort to head off dinos or will that just feed the beast of GHA?
