Silicone/sump
 

Hi i am diying my sump/refuge it is 20gallon tank dose anyone have any suggestion on a layout and can u use any silicon from homedepot or do I have to get some from the fish store

Use the search button for "silicone", there have been several recent threads about it. Essentially, no, you can't just use any silicone.

Have a look at this thread - http://www.canreef.com/vbulletin/sho...d.php?t=104362

Good luck!

I use this one

Not sure I'd build a tank with It but for installing baffles it does the trick. And at least is says aquarium safe.
