Planning a Closed Loop and Calfo Overflow

Names Brucey · 11/30/2009, 12:54 PM

I am getting ready to move my Oceanic 180 gallon and want to take the time to plan out a closed loop and install a Calfo overflow using Beans silent method.

I have no experience with either of these systems and would like some feedback on pump sizes, bulkhead sizes, and overflow designs. Any help or guidance would much appreciated. Thanks!!

Best advice I can give is to use unions wherever possible. They're worth their weight in gold when you need to remove something later, so go ahead and spend the money now. Personally, I also prefer threaded connections over slip connections that require glue-up. If you want to change something later, it's much simpler to unscrew a part and replace it with something else than having to cut out the unwanted part. Yes, leaks are a greater risk with threads, but that's where teflon tape and silicone come in.

My two cents' worth. Good luck!

Thanks. I am looking for any advise at this point. I am thinking of a Reeflo Snapper for my return and possibly a dart for the CL. Are there any other alternatives to the OM 4 or 8 way's?
