I am needing some advice and or formulas for calculating the volume of air I would need to properly aerate a 300 gallon IBC as of fish tank.
Any equipment to stay away from etc.
I have a Wisper AP 300 and am quite pleased with it. Been in operation just about a year with no issues at all. You can replace the diaphram if needed. With an IBC you want a deep water pump because they are so deep. Make sure what ever you get that it is rated for the depth you have.
I don't use formulas. I watch my fish. If they spend too much time at the top the DO (disolved oxygen) is too low. One good large airstone per 300 gallons is good. You want to get a good uplift to keep particulates in suspension so they can be removed.
I like air curtains ...... the past few air stones I've bought have broken when removing the airline to move it to a different tank ..... I have no problems with the air curtains ........ and they come in several sizes
I use the Linux Operating System ...... Free as in beer!

I'm not sure what you are referring to, but I've tried those plastic tubes that make lots of bubbles. They clog quickly. Large air stones last much better than the little peanut ones. My 6" stones are over a year old and going strong.
That is a regenerative blower. They normally can't push past about 24" but the can suck as well as blow. They are fantasic at putting out volume and are very reliable.
