What size are you thinking? What are you planning on running in your sump as far as equipment? You gonna run a refugium or frag area in there? Whats your thoughts and plans so far?
So far the only thing I have planned is the size of my tank and were it will go,I went with the biggest tank for the space I have.
My first idea was not to have a sump, but has i read I realise I will need one.But the wayI intend to install my tank my sump will have to be beside my tank,on the same level.For size I think I could go with about 30-35 g.If my sump is beside my tank is that a probleme?Is it best to have it perced or can I do with out the percing?
