Thanks for the replys.

I did dose KNO3 after the blackout. I am thinking that the C02 isn't high enough and that aloud the BGA to return.

I dose
KNO3 1 tablespoon Sat-Mon-Wed
K2SO4 1 tablespoon Sat-Mon-Wed
KH2PO4 1/4 teaspoon Sat-Mon-Wed
CSM+B 1/4 teaspoon Sun-Tues-Thurs

50% Water changes on Saturday.

I was also doesing to much KH2PO4 when I first got started. I don't have anyway of testing for phosphates out of the tap. There is alot of farming around here so I am guessing that the phosphate level in the tap is high. I am going to cut back on KH2PO4 and see if it works.

I am going to do another blackout along with a new reactor and start over again.
