Herbie's
 

I found an awesome strainer @ Gregg Distributors for my Herbie overflows. The holes are small enough to keep out snails and crabs and big enough that algae should not pose a problem. It has a factory 2" female thread which I used a male bushing to reduce.

One note is that this strainer has a 5" diameter so it won't work unless you have a big enough overflow.

I used the 2" version of those strainers on the 2" intakes to my closed loops. Each CL has a Dart pulling diectly through one of those strainers and doesn't create ANY dangerous suction over the strainer at all. I'm confident that an anemone could park itself over a large part of the strainer and be just fine.

set up
 

Here's my tank. Finally up and running. I ended up going with the Herbie style overflows and they're whisper quiet. Definately the way to go. Check out the monster piece of Tonga Live rock (left top,23lbs). I've gotta give a BIG thanks to guys at Aquarium Illusions for all the help with set up, that big piece of rock and all the information before, during and after the build. I'm starting to find that the available knowledge in that store makes spending a bit more money worth it. The majority of my Edmonton based aquarium business will be done there. Thanks as well to Ocean City in Cowtown for the quality craftsmanship on the tank, stand and sump. Finally thanks to everyone on Canreef for all the input, info and ideas. This tank wouldn't have turned out so well without it. Here's some pics.
