New to reef ready tanks..90 AGA planning

New 90 gallon AGA setup..questions regarding plumbing

Have my new 90 gallon in the garage while I paint the stand. My ignorance revolves around the plumbing into the sump. My previous tank that was up for 2 years was not drill or reef ready.. Just ran an aqua c remora that did great and had everything hanging off the back.

So, there is the whole megaflow area in the tank. 2 holes in the bottom where I will have water input and output from the sump. I have a Mag 7 as the return pump and I have a couple of questions.

1) Is the black megaflow area in the tank sealed so that the water only overflows from the top or does water actually flow into this area from the bottom, middle and top? (more of a curiosity question)

2) I have a 15 gallon sump. The skimmer is an aqua c pro w/ mag 3 hanging off the back of the sump. The output pipe fed from the sump into the tank isn’t really an issue since I will be running the pipe into the tank to use as some of the flow.

3) The water input into the sump is the part of the equation that concerns me. The pipe in the megaflow area of the tank that is going to be feeding the sump, what height level should I put the water input? I am assuming I don’t want the tube too low, but not to high either.

4) I do plan on having a valve someplace from the main tank output going into the sump. What kind of valve is best?

If someone could throw me a link to the best way of setting this up, it would be greatly appreciated. I have not had good luck w/ google..

Here's a link to the All-Glass Web site that may help you get some ideas on how to plumb your overflow:

In particular, click on the turquoise "Operation" button and you'll see a diagram of the overflow from the side and how it works.

Hope this helps you out a bit.

Thanks K9..I am debating if I just want to build it myself or buy the kit.

The diagram helped a lot explaining how it all works..

So you don't have the overflow(s) yet? Just the holes?

To use the skimmer in your sump you can just get a longer hose to attach the pump to the body. This will allow the pump to work at lower water levels.

jer77, the tank did come with the over flow, but the accessory kit was not included or an option(although I found it on ebay), just the two holes pre-drilled.

I went out over lunch and grabbed two pieces of PVC (3/4 & 1 inch) and a bunch of elbows..12 bucks.

Buy the kit.

It's more money but less headaches and the drain pipe is height adjustable Also the bulkheads in the kit are special. Normal bukheads wont fit.

Here are the progress pics of my 90g AGA RR tank that might help you.

Thanks xenon. After rummaging around at Home depot and doing some further research online, I ended up buying the kit.

Your build looks great! I should have some shots of mine up sometime in the next week or two!
