What to do when C02 is down
In my 75 gallon I dose EI and run C02. My light is a 65x4 Coralife pc fixture which is medium light per Hoppy's chart.
My problem is that when my C02 runs out and I take it to get filled the next day, staghorn algae appears. When I switched from a diffuser to a reactor I had one day of tuning the C02 levels, staghorn appeared. For me, 1 single day of C02 inconsistency causes PITA staghorn in an otherwise algae free tank.
Should I turn lights off on a day when I have to go get C02 filled? Is there any trick to not getting staghorn?
