Return setup on 120g Oceanic

[Spyral74]

Hi folks... I'm in the process of setting up a new 120g Oceanic with dual megaflows (1" drain, 3/4" return) and a Mag18 return in sump. My original plan was to tee the return to 2 SCWDs, one mounted in each overflow for 4 outputs, but I'm rethinking this now based on feedback I'm hearing regarding the significant head loss of the SCWDs and their instability.

What are the thoughts here on the SCWD config and perhaps instead setting up a 4-way OM squirt, or any other options? If I go with the squirt, what's the recommended setup? Do I use both the 3/4" and 1" in one overflow for drainage, and in the other Megaflow plumb the return through the 1" to the squirt and use the other 3/4" as a drain? Any other ideas?

Thanks!

I have a dual overflow 150 that I have a sea swirl on one return and a regular return on the other (loc line). I have a big return pump (sequence) that pushes water to both. I really like the Sea Swirl and wish I had 2 of them.

Thanks. Need to look into the Sea Swirls, but I really like the 4 outputs of the squirt for coverage. Anybody else want to chime in?

A Mag-18 may overpower an OM Squirt.

Have you tried the forum boards on their web site? Will get alot of info there.

I was planning on installing a bypass to avoid overdriving the squirt as recommended on the OM site, and to effectively serve as a fifth head. Also, looked at the forums there, but didn't see anything specific to drainage recommendation in a dual overflow setup. Will check again... :)

Perhaps another solution is to tee the return with a sea swirl on one side and the squirt on the other. Hmm...

Thanks,
Rob
