you set it to work opposite your lighting schedule....a reverse lighting cycle
not sure was thinking one rw4 would be fine but i do have my other one i can hooked up. i was going to ask this question about power heads. i see many people have them on the back wall. is it better on the back wall or the side?Looks good james....gonna add another wave pump?
Not to be a worry wart, but isn't salt exposure going to be an issue with an exposed power strip behind the tank, esp. with a HOB? GFCI or not, salt and electricity don't mix well out of the aquarium. Would hate for your tank dreams to go up in flames. [emoji91][emoji228] [emoji91]Hang on fruge came in. Now just to get sand and get the water going. Also need to get some macro.
