I'm about to add a JBL CO2 system to my tank and was wondering what the current thinking was on diffuser placement, i was going to stick it under the filter intake but is likely to interfear with the anarobic bacteria in the filter medium in any way? i'm now thinking it may be better to put it under the spray bar to wash the tiny bubbles over the plants :? :?
What works for you guys?
