My 20g long fuge idea

Okay well I am only putting a fuge under my tank because there is not enough space for a skimmer, all of them are too tall. Here is my plan in the image below, should I add another baffle before the return section? The return pump is a eheim compact 160gph.

anyone?

 

i wouldnt i am in the process of building one out of a 55 and im adding an extra baffle to get rid of the micro bubbles if theres nothing to make micro bubbles its just a waste of materials IMO, but i would put filter media to keep sand out of the pump to keep it from getting torn up.

 

hmm nice idea; are you gonna raise pods there?

 

Do you think I should take out the second baffle on the return section and have it just overflow over the first one? Also my flow isnt going to be too fast so I think the sand will stay put.

Yep ;D

 

any other opinions and would it be ok to only go 4in on the deep sand bed?

 

The largest issue with that design is there is no way to control the flow through the fuge section. check out this thread for a great design that will work well adapted to your 20L.

Awesome links, I will put a ball valve on the line from the overflow.

 

I think 4 inches is fine; usually its like 4-6 inches

 

Restrict the return, never the overflow.
