OK I am gonna chime in, even as a NOOB I have learned that if you bandage to problem it will still be there. Using a chemical to kill a bacteria wont stop it from coming back. I have a diatoms issue in my sand, everyday I get home from work and the sand is hazybrom. HAD a cyano/slime issue, treaded with chemiclean and it worked for a couple weeks. came back a little. OVERFEEDING will do that. NOT treating the problem by eliminating the cause will NOT treat the problem. I am NOT saying I know how to but I am saying that chemically treating will not help keep it away. the ROOT cause, I was told over and over, MUST be found. for me I beive, overfeeding my tank.
OH YEAH and I found Red Sea no3po4x!! It is the SINGLE most FANTASTIC NITRATE, PHOSPHATE reducer EVER! Better than VSV, better than Chemipurebag, BETTER than Carbon reactor. and it REALLY started to reduse my Diatomsand bloom!!
Must have a skimmer set up to use it. got my nitrates down from 20 to less than five in under two weeks! I still have diatoms every day, but my tank is 6 months old so.... and right NOW my TP is ammon, casue I think I lost a snail and had a small spike. ALso lost two fish to I believe ICH. I am treating with Microbelift myself, for another 6 days, then the skimmer comes back online and the NO3PO4X Gets back in gear. YOU GUYS HAVE TO TRY THIS STUFF!!!
