FWIW my first attempt at fixing the problem would be getting rid of the air stones, switch to membrane diffusers and leave everything else in your original system alone. I base this recommendation on the fact that the vast majority of the folks that post here on the forum that aerate have membrane diffusers and do not report your short 90 days to clog problem. Hey, if it doesn't work you can always pursue your LP tank idea. Since you were already planning to buy membrane diffusers, it won't cost you anything to try the proven method first before going to the LP tanks.

Just my 1 cent....

Have you calculated how big the LP tanks will need to be to supply the required quantity of air and how long it will take to fill them?
