Since my Fluval Edge had a leak I decided to get a new tank to replace it using the same sump and stand I already had. Once I broke down the edge I found out that the "leak" was actually just a spot in the overflow box that was splashing... But I like the new tank much better to be honest. For plumbing I decided to drill the back of the tank for the return and build an external overflow for the drain. Mainly because the tank is so small I didn't want to lose any space with a standard in tank overflow box. In the tank I have roughly 8-10 lbs of sand and about 8 lbs of live rock. The live rock all came out of either my edge when I broke it down or from the sump of my big tank. While the sand I've had in a bucket ever since I bought to much for my big tank about 8 months ago. I tacked the rocks together with super glue so they wouldn't shift and I could remove them if need be. Now just to add water and let the cycle begin!
