Tank is 135 gallon (I would hate it all to empty on the floor where the pumps are)
Four airstones (for oxygenation, thus 4 air lines).
Check valves are cheap (about $1.25 each), so is it good idea to put two in each line in series? That way if one fails then the other might prevent any backwards water flow?
Or is this not a good idea for some reason?
