I use a threaded PVC connectors and a boatload of teflon tape. Works great. Everything fed from the CA reactor and auto-top off are above the sump water line anyways...

I put a small bulkhead on my ATO tank and use uniseals on my skimmer. Both work fine. I'm planning on using John Guest fittings on my next project (either a Kalk or Ca reactor, depending on whether I can swing the CO2 paraphernalia after paying the Xmas bills).
