One more thing - the diffuser that we have is air stones(4) instead of a disc. I have seen a disc that is to be used as a replacement for the air stones assembly, and says that it does a better job. We were thinking of getting the disc and swapping it out with the air stones (deep end)and then moving the air stone assembly up around 5 foot depth. My husband is even thinking about getting 3 or 4 discs and a larger compressor.
Would that be a smart move?
