Well even with the new pump and better flow the stuff still seemings to be growing without any problem. I have added "marine buffer" a few times since i started the tank to maintain my PH. Could this have something in it that would fuel the cyano
? I'm just throwing things out there trying to figure out what the source could be. I've cut feedings down to once a day and not much at all. Clown finish it up within 30-40 seconds.
edit: another quick thought. The cyano
is only growing in the sand. I don't see it anywhere else. Could there be something leeching out of that sand?
