AI Sol White - Cause Cyano?

[zoolan70]

I recently changed my frag tank over from halide to a Sol White. Since then, I've had a huge outbreak of cyano, but only in the frag tank, not the connected DT. At first I thought it may be due to the turnover rate from the frag tank to the DT, but it is now well over 10x the volume.

Can the setting on the AI be causing this?

Thanks!

Not likely.

You only have 10x total turnover in the frag tank? Increasing flow can help with cyano.

10x turnover from main to frag. I also have 2 powerheads in the frag tank itself. I'll rearrange them and see if I can get it under control...

how are your phosphate levels? I have found cyano likes phosphates and low flow.
