How does BH location play into it? I just finished drilling the back glass of my tank this weekend but I'm interested in your comments on my set-up.


I will be using a Dart pump, OM-4-way, and there will be another 2 1" holes in the front of the bottom glass of the tank.

It's all a question of available space. If the bulkhead is to close to the corner the Tee plus the starter loc-line fitting and then the loc-line wont be able to clear the corner. I think you should be good but I'll grab a length of my 3/4" loc line and test the radius and I'll get back to you on it. Are you 100% sure that the bottom of the tank is not tempered. If it is you're going to hear a big snap when you touch it with a drill bit. My 75g is bottom tempered and thats why I drilled the tank at the rear down low and ran the pipe under my sandbed to the front of the tank. It has 4 outlets spaced across the front.

I was sitting around last night playing on my computer and looking at my tanks so I thought that I would give it a try to draw up my own sump. Let me know what you think of it. I know its the design of alot of others out there but will the size work for my 90gal that Im starting to build. Any input on it would be great I take the good and the bad but if its bad please let me know why so I can try and fix it.

everything looks great. I would personally make the fuge baffle higher and if your using acrylic add teeth so the macro doesnt wash over the top and clog your pump. Certain insump skimmers require a specific depth of water to operate properly so remember to take that into account when sizing the bubble trap. some people end up building a platform to get the skimmer at the right height.

I forgot to say that yes that size should be just fine as a sump for your 90g. The biggest concern with sump size is, will it hold the water that will end up in it when you have a power failure and your pumps shut down. You'll be surprised how much water is in motion when your pumps are running. There is more water than just whats in the pipes and the overflow box. Figure the area of the top of your tank times possibly 3/4" to 1" that the teeth will hold back. The fuge is allready full, The skimmer section is full, this leaves just your return section to hold all the water that is going to be coming down the pipes.

Them are some good points that you made there 2frosty4u. I looked at the skimmer that I want and it has a water height of 9" so I think I will make the top of the baffels at 9 1/4". I was planning on putting on teeth for the fuge side but Im not sure how high to make it right now. But if its 9 1/4" from the top of the baffles that will leave me with just under 5" for water to drain into it of there is a power outage.

why drill for returns when you can just run them up the back of the tank and use back to back elbows with snap lock to disperse the water?

I never really thought of that. That is a another idea that I have to bounce around in my head. Thanks for bring that up thehunt!
