sorry am not sure i understand your question

Those are the stats for the Fluval canister filter if I'm reading correctly. Powerheads won't hurt, but you may not need them - how is the circulation in the tank? Any dead spots? If the water is moving through the entire tank and keeping detritus suspended so the filter/skimmer can take care of it, you're gold. If there are slow or dead spots, that's where a PH would come in handy
