[APD] Tank blackout and making sure fish get enough Oxygen
Hello, I was thinking of doing a tank blackout (to help with a persistent
greenspot/dust algae) while I was away on a 5 day trip and doing a good
prune when I get back.
My worry though is the fish getting enough oxygen during the blackout as the
plants won't be making any. I'd say I have a med fish load. Any ideas?
I'll probably use a towel on the top of the tank and leave 1/2 of the glass
cover open but not sure if that allows enough air to circulate. I have a
spray bar which I could raise to get heavy surface agitation.
Tank is 90 gal, heavily planted.
