Folks, if you've recently upgraded or renewed your annual club membership but it's still not active, please reach out to the BOD or a moderator. The PayPal system has a slight bug which it doesn't allow it to activate the account on it's own.
You could use a mag 7 and then go with the 700 gph overflow. With the 90g we have, we went with the 1500 gph overflow. Here's a pic so you can see how small it is:
Also, you could go to our tale of the tank and see the 90g build. The drilling of the tank is on the first page, while the...
I'm confused...and that's pretty easy to do. Having an internal or external overflow is not going to determine the means of filtration. When we had the 46 bowfront with an external HOB overflow, we had a 40 g breeder as a sump/refugium. When we moved over to the 90, with an internal overflow...
Welcome! First off, a one inch Sch 40 bulkhead needs a 1 3/4 inch hole. But wait...what we did was buy an overflow kit from www.glass-holes.com. It not only comes with the overflow, bulkheads and elbows, but includes the bit to drill the tank. The units are small and take up little room in...
Give us some more detail...size of the sump; pump flow rating; type of skimmer.
The tang police will get on you with a sailfin and hippo in a 50 gallon tank. I have to imagine they are small now. You might want to consider an upgrade in the future.
I'm in agreement with RichT. This thread has reached its constructive conclusion. If anyone would like to add to this discussion, please PM one of the moderators. Thanks.

You do not want to use Silicone II. It's not the smell that is bad...using the right silicone will smell for a while but is still safe for your aquarium. What is bad in Silicone II, and almost all other "construction" silicones, are the antifungal and/or antimicrobial agents that are added...
For the life of me, I can’t see how you could have stagnant water in a sump/refugium. Pictures would really help here. You’re running a mag 7 that, for the sake of discussion, let’s say is pushing 500 gph of water after head loss. That’s how much water is moving through your sump. Baffles only...
The majority of the surface area of the live rock is not on the surface of the rock. It is extremely porous, with the majority of the surface area internal to the rock. The bacteria are still flourishing within the rock. Even completely covered, that rock is still a churning bacterial factory.
