I appreciate the replies.
I actually went to OSH (by Arden) before I had a chance to read any of the replies. They had some fittings but not the size that I need. I could not wait so I jerry rigged some of the fittings and hopefully it works.
I have all of my corals in the garage while I'm doing my upgrade so I need to hurry up before I lose all my corals to heat. It seems like the first one to go is my PPE frag. Crap, I baby sat this frag for 2 months before it even opened up. Now, I'm just goin to lose this critter to heat.
I'm just not smart enough for this hobby or I would have gotten a chiller before the upgrade.
Thanks again for the replies!
