this is my 240
theres about 12 bags of b balls.
bucket is full of b balls also.
the whole left side of the sump where the bucket is will have a huge b ball box above it this weekend.
heres the netting i used to make the bags.
bought it at a fabric store.
nylon netting 99 cents a yard.
lay balls in and fold it up then put 2 rubberbands on each one.
those aren't the best option for hob filters....really they are pretty horrible for small spaces like that. they are also much better when they aren't completely submerged and water is just rained on them pretty much. hence why they are used in wet dry's.
thats all edwin
x24,i submerge most of my media and bio balls must do something or they wouldnt be called bio balls
and i think b ball go both ways.lol
oh and i didnt buy these so it was worth it
