20g reef with a 5g-10g sump/ refugium
Basically I originally wanted to make my new fluval spec 19l into a small reef... But as its so small i cant keep the fish i would like so i wanna start a 20g potentially!
If anyone could run through the set up required and equipment that would he so helpful!
I know how to maintain saltwater aquariums as I have researched a lot! But even though i have researched dumps i am still not sure on how to set them up and what is required for a 20g tank?
