I’m currently in my 2nd month of reefing. I am running a 10 gallon innovative marine nuvo 10 with no skimmer and an ai prime HD. For filtration, I’m running two bags of chemipure blue nano, Marinepure gems, and filter floss which I change out weekly with a 2 gallon water change.
I’ve gone through a good portion of the cycle, experienced the diatom phase, and am currently battling new tank cyano. From my understanding, cyano is fairly common in new tanks and I was just curious, how long this stage lasts, and how much is a normal amount of cyano when setting up a new tank? I use 0 TDS rodi water. Should I resort to using chemiclean or run some GFO? Or should I just keep up with the water changes and maintenance until it disappears?
the cyano mainly grows on the sandbed which I stir up every other day, and siphon during my water change. On the rocks, I’m seeing some coralline algae starting to grow which I think can be a good sign?
Im not sure if my flow is a problem, because i use a random flow generator at 326 gph (32x turnover). However there is one deadspot where some detritus settles but I cant be bothered to add a powerhead to this small tank I reduced the intesnity of the lighting and duration to ~10 hours (1.5 hr ramp up and ramp down, 4-5 hours at peak intensity (about 60%). I’m new to this and would love to learn more!
my parameters are in check (except an issue with phosphates):
Alk 7.7
Ca 430
Mg 1260
Phosphate 0.00 (undectable, not sure if cyano is sucking up the phosphates quicker than I can test using a hanna checker.)
Nitrate 5ppm
Salinity 1.026
pH 8.2-8.3
