i have a 65 gallon tall with a penguin 330 and some Lifetech Power head with a filter attached to the bottom. The power head is rated at 1100litres/hour. should i invest in another filter? possibly another penguin 330? right now i have about 20 little cichlids in it. thanks
I have a 4' 50 gallon with a millennium 3000 and a rio 600 powerhead with a sponge filter on it and the water is nice and clean so far. Stocklist in my signature. What is the Gallons per hour on the penguin?
