I guess the first question is, do I really need to ryun a fuge on a 100g fish and softies tank with a 1-2" sand bed? If the answer is yes then check out my plans below. What Im thinking of is a 33x13.5x13 sump and a 16x14x13 fuge. The fuge would have 2- 1" bulkheads draining into the return section of the sump. Im just not sure if this is an optimal setup or not?

looks like a neat concept.

nice concept but I would only have one drain from refug. do not want a lot of flow there

Looks good-just put a ball valve on the inlet to the fuge so you can limit the flow there and leave the 2 drains into the sump. Make sure to put some type of screen over the drains so that larger critters/algea dont plug the drains or get into the sump. The 2 drains would be safer than 1 in case the flow is reduced or cut off on 1 from algea etc...

Simple enough to add a ball valve before the fuge. If I do it after the "t" it shouldnt really affect flow to the sump, right? I think the 2 drain are safer than 1, besides the ball valve would be used to control the flow.; Are 1" blukheads the correct size?

Would there be some way to "cover" the drain area to prevent blockage without restricting flow? Like an acrylic "box" with teeth like an overflow? But then how would pods get into the return chamber to get pushed into the display tank?

My only other concern would be building a "fail-safe" into the system.....
