What size return pump will I need, with a 1/2" drain, at approximately 3'? I drilled the back of my tank (so easy I didn't even feel the overwhelming sense of accomplishment that I expected). I diy'd the box with "black glass" and silicone, with dimensions that I generated fairly randomly...working though
20 long tank
Also... Suggestions on lighting for a 20 long? For "high" light... does it really need quad t5ho's or can I get away with a dual?
