Hey All,
I am having a problem with phosphates. Currently phosphates are running around 0.7 and nitrates are at 20. I believe this is causing my problem with cyano. I don't have a phosphate reactor but I do have a sump setup with a refugium section (about 10 gallons). In the refugium is a little bit of caluerpa and a little bit of chaeto. I just (tonight) hooked up a 100w equivalent CF 6500K daylight bulb over the refugium on at opposite times as the main 90 gallon tank.
My question is, if I can get the chaeto to grow out, will it reduce my phosphate problems or will I need a phosphate reactor? Thanks in advance for any help.
