I have 3 things i'm debating that i'd love impute on.
I have a 4blub TV hybrid fixture to go along with my G4Pro radions. I have 4 G4s but I think that may be overkill and I only need 3 on my 220. I could put the other G4 on my frag tank. Thoughts?
I have a hammerhead pump but i'm debating returning it and getting to internal pumps instead. Maybe the echo tech pumps. I'd do one pump for my 220, and one pump for my 50 gallon, frag, and manifold. Two pumps would be more expensive but it may give me more flexibility. I also wouldn't have to drill my nice new sump.
I've never done automatic water changes before and i'm debating if I want to or not. I'd love to not have to do big water changes but in 10 years of reefing i've never done auto water changes so i'm nervous to jump in.
In the fish room I put thick plywood up on the walls to mount everything too. I'm wanting the concrete and the walls white, but haven't decided if i'm going to paint the plywood white or not. I thought I might do it black to give some contrast with my red plumbing.
The thing i'm struggling with most is how much I forgot since I was neck deep in tanks. I thought it would be more like remembering how to ride a bike then it has been.
Exhaust fan is a great bonus for the room. I personally dont like gfi outlets for a fish tank unless you get wifi ones to alert you of it swithing off and you have a battery backup on some powerheads.
Even without gfi outlets you should have battery backups though.
