Night time hypoxia?

Do any of you folks worry about hypoxia in fish in a heavily planted tank at night... do you run an air stone at night for this?

My set up: heavily planted 29 gallon, 110 watts PC, 1.5 - 2 bbs/sec CO2 with Reactor 2000 diffusor, 7 kH, pH 7.8 (maybe really 7.4) in the AM, drops to 6.9 pH where CO2 shuts off with Milwaukee controller. CO2 system not run in the PM (on a timer synced to lights). I am running a Biowheel now (I know I lose some CO2), which I will leave for the moment for night time surface agitation.

The only time I would worry about hypoxia is if I left C02 running all night without surface aggitation, my pipe's and spraybars get raised to the surface at lights out and lowered in the morning's, doing it this way give's plenty of 02, and kill's surface scum.
