Re: [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.
Thanks
Peter.
Pete,
I went thru a 7 day blackout earlier this spring (during the big ice storm
here in oakland county in march) I had my heavily planted 90 gal wrapped
in a giant quilt for 6 days and the only source of air was a battery
powered air pump attached to an airstone. I did have *some* losses in that
tank but i attribute it to simply getting to cold (the tank got to approx
53* F - other smaller tanks were colder). In fact the only losses i DID
incur in that tank were my discus and altums. I think if you did turn your
spraybar up like you mentioned, that would be more than adequate, but if
you've an extra air pump around there - better safe than sorry. This would
also give you a "fresh" air source entering the tank, focing at least some
of the old stale air outa the cover area for you.
My $0.02 USD. BOL, YMMV ;)
