I am not cutting down salt lol what size of tank is it smaller tanks need surface agitation to release the c02 out of. The whater smaller tanks leess whater volume changes a lot easier and faster than lots of water I cured me problem switching to a hang on the back filter all I run is the aqua clear 70 on my. 30 run. The sponge and then just filter floss from a fabric shop. Gives you a break in the surface and crystal clear water
