So, I should be setting up the tank tomorrow. I just wanted some suggestions. The sump is a truflo 180. I think its about 40gls. Should I run it with the bioballs as a wet/dry, or should I take them out and fill it with live rock??? The sump has 2 holes drilled on the bottom of the right side, as you can see in the pic. I am going to seal them unless someone tells me they will be usefull! I dont have another sump at the moment but I wanted to run a refugium. Can I run one in this sump??? Also I want to eventually run a calcium reactor. I have the bulkheads that fit the holes but no plugs. Would love some suggestions!!!!

I have removed the top of the canopy and was thinking about hanging the lights using yo-yo's so I can raise and lower them with ease. And was planning on having them sit about 4 inches off the tank flush with the top of the canopy. Was planning on cutting out 2, 3 inch circles on each side of the canopy that will house cooling fans! what do you think????
