I bought the Aquaclear 70 yesterday, plus I have a sponge in the opposite corner. Right now I have 2 jewel cichlids and 2 blood parrots in the tank.Are you wanting to run the Aquaclear as a 2nd filter in conjunction with the C4, or run it as the sole filter? I run some Aquaclears, I like them.
What type of cichlids do you have ?
You're on the fast track having 3 tanks in 2 months! I forsee you building some double stacked tank racks this summer when your collection approaches a dozen, ha !
The forum calls it MTS... Multiple Tank Syndrome.
