Hi, I've just bought a second hand 500 litre tank that has a sump already built in right along the back of it? Does anyone have experience with this kind, all my google searches just bring up the ones underneath. I have a feeling I may need a bit of advice on setting it up when it arrives at the weekend as I have no experience with sumps as it is.
I will be transferring over my current stock from my 55 gallon but that doesn't have a sump.
