Is there a different with submerge bio ball (sump) or above water line (wet and dry)? Issue of BB or oxygen exchange between the two method. Thanks

The submerged setup steals O2 from the water whereas the semi-submerged setup uses atmospheric O2. The latter method is more efficient on a inch for inch basis. Not good for a planted tank though (you don't want heavy oxygenation or degassing there).
my bio-ball is submerge in my sump. Would i need to add an air stone of sort to generate 02 for BB? Wouldn't the drip plate, over flow box and pump generate enough 02?
I'm running a large sump ( 120g) with a 40g for the bio-ball. I've 3 section with gravel pond mat and charcoal. My tank is 500g with a 3x turnover per hrs. I have mostly fish some plant. I've been running this tank for about 4week but my Ph has drop as i expected. I suspect it might be the O2 for BB..

I've often wondered this also as with my wet/dry area the water ends up channeling so only parts of the bioballs will get the water over it.
skynoch......... You need to adjust your drip tray so all bio-ball surface get water trickle or the bio-ball is not doing it's job.
It seems either the drip tray or the bioballs need shifting constantly or the water finds the least path of resistance and channels again. lol must be doing something wrong.DDragon888;4056513; said:
