You might really consider a moisture tight enclosure for your apex base and EB8's. It might be an expense you didnt intend to have, but hey, isn't that kinda par for the course with reefing ? Saltwater vapor + non-waterproof electronics = poof, and when you consider that your apex setup is *at least* $500, probably more like $750, you want that to last as long as possible.
