i am just starting my planted aquarium and i need to get a new filter! my old one is okay but not that good, i want one to keep the tank nice and clean! i have a 30 gallon tank, i was looking at a Whisper 60. in the item description it says Good for aquariums up to 60 gallons. Pumps 330 gph so that should be okay right? what about ultra activated carbon? is that going to effect the c02 in my tank or the plant ferterlizer?
