anti SBP solution?

hi all

i used to put ard 5 airstones and 3 sponge filters (beside my IOS) in my 6ft comm tank....then lately 2 of them got suspected SBP. with this configuration, they creatd alooooooot of bubbles on the surface. As aros are surface swimmers, i suspected they take in alot of these bubbles as well

right now, i have been using 2 sponge filters only....conditions got improved abit....and i feed lesser also....

my 2cents worth of sharing....

cheers
