Bought a 10 gal during the PetCo's $1 sale drilled it for a return pump and added baffles to use as a sump. Thing came out AWESOME! Noticed a little salt crawl around the bulkhead today, wiped it off and saw a freakin crack! So rather than buying another one, re-doing the baffles and drilling it again I think I'm just going to pick up a small acrylic sump if anyone has one that they are upgrading or breaking down. let me know what you have, I'm slightly limited on space so include dimensions please.
