Recently I placed an order with a mailorder company. I ordered a package to two airstones, and they sent me the Tetra AS1's instead of the AS2's. The AS1's are supposed to be for undergravel filters, while the AS2's are for general aeration.
I wanted airstones for general aeration. Does anyone know if these AS1's will work fine for general aeration, or is there something special about them that makes them only fit for use with undergravel filters?
