So I'm about a month into the great hobby and the second hand canister filter that I'm running spung a pretty bad leak. It was a nightmare. So I decided to design and build my first sump. 20 gallon long with a Fiji cube sock holder, AI axis90 return pump and a max spect refugium light. Cut and glued in the glass baffles and made a 3 piece lid for it as well. All the BRS TV videos have been so helpful. Love watching those guys
