So....I know cyano is not a algae but figured I could put it here. I have some small patches of cyano in the lower flow areas of my tank. Trying to figure out what is causing it. My water source is perfectly fine, no readings on phostphate or nitrate. I have one mp10 set on reef crest at 80% so around lets say 1200 gph and a wp25 set on w1 so another 1400gph or so plus the return about 55x turnover. My tank is 24x22x22 50 gallons. I have 5 fish in the tank 1 cryptic wrasse, 1 possum wrasse, 1 diamond goby and 2 clowns. I feed about a nickel size of lrs reef frenzy or the same amount of rods a day and feed the coral with oysterfeast mixed with reef frenzy or rods 3 times a week. My rock was dry rock from marcos rock. The tank is 5 months old. Lights run from 7:30 in the morning to 7:00 at night. Reef radiance 120 pro. I do a 10% water change weekly and syphon what I can get to out. Small clean up crew but nothing eats cyano anyway.
Testing 0 phostphates and 2-3 nitrates. Have a skimmer rated for a 150 tank and running GFO(Changed bi-weekly) and have chaeto in the sump. What might be feeding this cyano? Sorry for the long post but wanted to get everything in there let me know if there is anything else you want to know. It is not taking over the tank by any means but I can see it getting a little worse and worse everyday.
Thanks in advance,
Aaron
