noob question...Air volume for sponge filters

[4eye gold fish]

Hi all,

Noob question... how much air volume do you all run on your sponges? I have mainly used HOBs or canisters but recently bought sponges for my breeding tank(s) and not sure if i am pumping too much air to them.

Aquaneat Aquarium Air Pump up to 300Gal w/Two Outlets Ultra Quiet Oxygen Aerator Pump
Output: 2x125GPH, with 2 outlets; Power: 10W; Pressure: 0.03Mpa

BACTO-SURGE HIGH DENSITY FOAM FILTER (2-Pack)

I have both outlets connected to a 4-outlet Gang Valve and feeding to two sponges.

thanks,

What size tank.

Hi Liz,

20 and 55

what I want to know is... how much air is sufficient for it to work efficiently and not create too strong of a current/wave in the tank.

thanks,

Put one sponge in for each tank turn the air down to med low on the 20 and med on the 55 then adjust as needed. You don't want a lot of current for Discus, just good surface movement.

Hi, if I seed another sponge filter from a cycled one, what are the chances of cross contamination?

thanks,
