pot scrubbers for sump

[Oddball]

i thought bioballs in a wet-dry promote the gas exchange proccess

Gas-exchange is purely the result of the air/water mixing state and dwell time. The longer moving water is in contact with air, the greater the amount of gas exchange. The material causing the agitated water condition is immaterial to the process.

I'm starting to think that you are no mere mortal Oddball, but a super-alien-computer-lifeform that walks in a skin of human flesh and just happens to enjoy the species we call fish!

Or you just have an insane wealth of knowledge, I like the alien computer thingy better though.

I'm just your average fish-keeper. Been doing this for 40+ years. There's nothing special about me...special about me...special about me.....

The point of bioballs is that they (should!) be cheap and hardwearing because they are made from lovely plastic (possibly not a good idea if you want to be enviromentally friendly). They also have a massive surface area because of all the grooves.

If you use them in the drip part of a wet/dry, then they will be colonised by the bacteria that converts ammonia to nitrites. This is an oxygen loving bacteria and does very well in these conditions - this is also why your bacteria in a canister filter dies off when there's no power to it

The bioballs themselves have no effect on gas exhange - it's where they are situated that makes the difference.

Oh, pot scrubbers of certain types, those plastic loofa thingies and of course stikka bricks work just as well. Make sure that you don't choose a pot scrubber that is biodegradable though!
