I know the standard is 1 watt of air power per gal on water. And You know how we like to overdo things. So how much air is to much? Can you have to much air? I am just wondering i went ot get a new air pump today and they didn't have the one I wanted. So I go the same model but bigger. It is 112w lol. My current res has 14 gal in it. Thats 8 watts per gal. It really gets the ole res bubbling.
The 1watt/gal is a fine rule of thumb, but it doesn't make a damn if the air isn't DIFFUSED. Plus a few degrees temp difference makes a drastic difference in the amount of dissolved oxygen the water can hold.
I'm working on the theory that you can't have too much.
I run commercial flex disc fine air diffusers that supposedly makes a million 3mm bubbles per cubic foot of air. Temp no more than 68.
