Planet now makes some pretty cool sizes and no plastic center brace. I never ran a calcium reactor, I tried my hand at a carbon reactor but removed it because my frogspawn did not like it. Not sure about the redsea lights, looks like you may need quite a few looking at their Par numbers on the BRS website. Good luck with your new build.
