It's only needed when you're running media that needs to be out of the water, like scrubbies or bio balls since you want water to drip evenly over all of the media. When running submerged ceramic media, it's not needed at all, and makes the sump much easier like I said.scallywag14;4526768;4526768 said:Does the drip trays work better or do you not even need a drip tray?
Well that depends what type of media you're tallking about. Submerged bio balls/scrubbies are no good beacuse they need high levels of oxygenation to grow bactera, hence the 'wet/dry drip' application.David R;4526832;4526832 said:IIRC, submerged media isn't as efficient as the above water trickle stuff, but obviously it still works well. If I just used submerged, how much do you think I'd need for the 370g tank, not super-heavily stocked? I have a 25kg box of ceramic noodles, plus a big box of bioballs and was planning on running about 50/50 submerged and above water.

I will try to make my next sump like this design with my filter sock 3/4 out of the water with no dividers. I see now y I do not need dividers.jcardona1;4526718; said:Ideally I'd say make sure your socks are 3/4 out of the water. They work better that way. The sump on my 150g had the sock almost all under water and I didnt like that.
As for the media, I like to use ceramic media now. It has to be submerged, so it makes building the sump very easy. No messy drip trays, dividers, and baffles needed. I'm never using bio balls or scrubbies again!![]()
