hydro sponge filter

[ward1066]

I got a couple of these today and do they eventually sink? I have tried to squeeze out as much air as possible but they still float. PIA to weight down. Does a air pump move enough water of should I use a powerhead. It is just supplimental mechanical filtration for breeding periods.


thanks

they will sink....eventually

powerhead if you want it for mechanical airpump works fine for bio

also soak them before you put in tank it helps

I finally got them to sink, kinda amazing the hydro V is rated for 125 gal. seems pretty weak looking with a air pump.

Depends on the air pump. I get what your saying though I am only using one sponge right now but its on a 10 gallon betta tank so I cant really say.

Never heard of it. Whats the CFM or PSI ? I am in love with my luft pumps I got recently safely adjustable and up to 7 psi fairly quiet just pricey at around 60 bucks.
