Ok so clown puke tank is going bye bye. I want to do a nice refugium With macroalgae and maybe mangroves, linked to the spec like this. Anyone who has done sumps, will a bulkhead in the plastic separator inside the spec work?
The red tube is the siphon and the blue is an airline run down PVC tubing to create a simple air lift pump that drains into the spec.
Or should I go with a traditional overflow, or try to drill the tank?
