I have read everything I can about cyano
, what to do, and how to get rid of it. It is all over the gravel and climbing the walls. Not on the corals, yet. Sorry I can't send a pic, but I just cleaned the tank and I didn't think. Before I cleaned I tested.
Temp 79 degrees
Nitrate 10 ppm
Alkalinity 6 dkh
I am running a 28 gallon cube. A month ago, we changed from the CFL that came with it to LED
's currently running at 40% cool white and 80% royal blue. Because I have been vacuuming out the cyano
so much, my 3 inch sandbed went to 1/2 inch in the four months I've had it. On August 7, I added gravel to half the tank. On the 15th, I added to the rest of the tank. Gravel was rinsed thoroughly, but the next day, cyano
was back. We even vacuumed our sump. Running the filter rack with fiber in top section, Chemi-Clean Blue in second, and a mixture of nitrate and phosphate sponges below Poly-Filter. Change 4-15 gallons of water every 5-8 days. Ok. Can't think of anything else. Corals are mixed softies, hard, SPS
. Fish are pajama cardinal, royal gramma, two clowns and purple firefish. Tank has been running for two years. Haven't added anything new for at least a year. I do not dose. I use ro
for everything with IO Reef Crystals. Long, but thorough.
any help, or am I just a dummy?
