i have a 55 gallon tank with 100 lbs of fiji rock and 60 lbs of argonite. nitrate, nitrite and amonia levels are zero. i do a 5 gallon water change every 7 days. my lights are 4 x 65w and are on 10 hours a day. i have a prizm protein skimmer and a fluval 404 canister filter. the cyano is maroon and i can't get rid of it. what can i do?

thanks in advance for your help,

What kind of water do you use (Tap, RO, ect.) to make your saltwater and for top off?

 

[kento]

i use bottled water from a local water bottle company. they assure me that it is RO.

i just check with my lfs and my phosphate levels are zero. they cannot do a redox test. they have some stuff to treat and get rid of the bacteria, however, they said i have to find the cause of the cyano.

Be careful with bottled water. Even plants that now use RO instead of distillation often still have copper tanks that they store the water in.

Increase flow to eliminate dead spaces and add phosban/rowaphos-see if that helps-
