My tank is a year old. A few weeks ago my green birdsnest started going downhill quick after a 2 month growth spurt. Then I started getting cyano. I ordered the hannah kits and just as I suspected my phosphate was 0.43 and my nitrates were 0.00. I turned off my skimmer and my UV and I lowered my fuge light from 18 hours to 6 hours. I then ordered neonitro from brightwell which arrived about a week later and the first day I dosed 8ml. Tested 24hrs later and phos was 0.10 and nitrate was 0.00. The second day I added 10ml of neonitro and tested 24hrs later. My numbers were phos 0.19 nitrate 0.00. I added the recommended dose again this morning. My question is once I get the No3 and Po4 to acceptable levels how do I maintenance dose neonitro? Also, is there something else I should be doing?
