Zero last month, but it looks like I'll have to buy a new kit as the colors look wrong now

All GHA is on the rocks with some on the props and overflow. Cyano on both

Not bad as far as I can tell. I have 3 MP10wES on 92%
I'll have to step up my housekeeping methods for awhile. I used to clean my sandbed but stopped when the diatoms wouldn't go away. Fat lot of good that did me

I forgot to mention something I found before starting this thread. And this issue for sure was not helping me;
My RO was showing 2 TDS and a Hanna test showed 0.002 in my storage drum
I cleaned the RO out and replaced the Membrane

I agree with needing to step up my WC amounts
