DSB in sump or no?


New member
Im running into issues after building a 75g sump. I feel like my flow through the 2nd section which is where I currently have some live rock and cheato is way too low on the botttom 2/3.

Deitrus just sits at the bottom with no flow. Would I be better to add a deep sand bed and then it would not have the same amount of water height which would create more flow in the top section.

If i went with a DSB what kind of maintenance do you have to do on them?

There isn't much maintenance, kind of a set it and forget it thing. Disturbing it can cause you some real problems after it's been in service a while. Do a bit of research before you get started with it though, the depth is important, too shallow and it'll be more trouble then its worth.
