I have an 18g and a sump system meant for a 100g. with a HOB overfow box. Should I convert a currently empty 10g tank into a sump/refuge? would that be something good to do?

what do you mean by "sump system"?

Since you have all the parts to make one I would do it.

Sealife System 100 Sump

HOB overflow, 15~ wet/dry with bio-balls, rio 2100 pump

I bought it when I was just going to do a 55-75g FOWLR tank but i decided to start with a smaller reef first. The sump is funny shaped so I can't easily turn it into a refuge (and I wanna keep it around for when I decide to get a larger FO tank).

not sure what the hob is. do you have a link to a pic of it?

If you do use it right now on the 18, do you plan on removing it later for the larger tank?

I got a green chromis..he's been hiding for the last 2 hours, and I bought 1/4lb of live rock debris covered in coraline.

if you plan on hooking it up to the 18 and keeping it there I say use it. Have you considered (since your stand seems tall enough) drilling the 10 gallon you have and hooking it up as a refuge?

maybe have the overflow leading into the 10 and have a stand pipe design draining into the 15 sump. Probally over kill but you have the pieces already.

See first post..thats what I had planned for the 10g...a sump/fuge. I hooked up the overflow box to the sump i have already. When I get around to getting some silicone and acrylic for the sump dividers, I will set up the 10g sump/fuge

oh okay, i must have totally misread all that stuff. You are just asking whetehr or not you should put a 10 gallon refuge under the tank, right?

I would.

Nah....its beside the tank...I was just wondering if I should go through the trouble of converting the 10g to a sump.
