Zeo and diatoms

What else are you dosing? OD on Aa, cv, xtra and fws will also cause brown film on glass. I also would agree on lowering your start dosage. I'm dosing 0.4ml twice per day for 120g heavy bioload tank. Also here's are link you might find useful.

Thanks I'll lay off the SP for a few weeks and see.
I'll cut back the zeo start to . 15 which was my starting dosage
As for other additive I was dosing half recommended and building up from there.
The problem was from beginning which Sp was the only extra additive I was using

Hope this worksss

Thank you
