Bio-Balls

I like to check out the no. of Bio-balls needed for a sump tank of size 2x2.5 ft. Any ideas? And roughly how much it would cost?

my sump is almost the same dimensions as urs.
My bio-balls are not submerged in water but trickle down in a conpartment (2feet x 1ft x 8inches) about 300++ bio balls.

But I have already removed 1/4 of the balls and replaced with dead rocks.

bio-balls are apparently good if u have high bio-load and fish only. but according to west, they suggest removing bio-balls and leave it to trickle down or replace with rocks.

I thought u might be interest.

Consider to replace the bio-ball to biohome or LR.
Bio-ball will accumulate NO3 only( Nitrate Factory ), it does not help breaking down to nitrogen gas.

Thanks.. i wan to check out the rough qty and price. Jus making sure i din get it too expensive.

hi, i thought removing the bioballs will kill the BB? if i have one bag of biohome and some bioballs on top of it, can i remove the bioballs and replace it with another bag of biohome?

Yes, you can remove the bioballs but do it slowly over a period of time. Replace the removed bioballs with some biohome each time you remove the bioballs.

If filter media is to be removed/replaced, they should be done slowly as removing/replacing the filter media at one go will remove most of the bbs found in the filter media.

Bro kalib.. how to add in the biohome slowly? is it by adding few piece of biohome slowly straight to the filter without puting inside the filter bag?

You can add in with the bag. Just make sure it won't replace more than 20% of the bioballs at a time.

The idea is to let the bbs populate the biohome before you replace another portion of the bioballs.

If all/most of the bbs are replaced in one go, there won't be sufficient bbs left to handle the tank's bioload, resulting in an ammonia spike.

So what is the true purpose of having Biohome...?
