First saltwater tank

[ckozma]

Well that section definitely needs a pump to pump the water out and some locline, that will keep water circulating though that section. Now you can measure that section and find a small skimmer that will fit in there similar to the small ones they make for biocubes. Another alternative will be a HOB, or hang on back skimmer.

Either use as a skimmer pickup section or remove that chamber.
If used as a sump overflow you would have to go U tube style and that alone I would not trust

I was thinking of putting the skimmer in there.
But this what I did so water wouldn't get stuck in there. In those holes/openings is where water gets inside of the overflow

I put a powerhead in there cause it sucks the water from one side and takes out to the tank.. Does that make sense

 

[ckozma]

Yes, it definitely needed the powerhead. Not too much room for a skimmer though, might have to use a hang on back.

This what was in there and took it out. What if I buy. A smaller skimmer and maybe have more WC? Would that work?
