Need advice on my DIY project 90

[jdoenumber2]

Well, I just got a new 90 gallon that was drilled on the back. What i am trying to do is make a dual over flow tank. So far this is what it looks like i will post pics as i move forward. I had purchased a storage tote made for storing wrapping paper and cut it in half and plan on painting it black and sealing it to my tank. From what i know i will need to drill the top of my durso's. My goal is to make this silent as possible. One thought i have is to drill 1 small hole in to all three caps connecting them with air hoses. I figured that by using a gate valve for the back i can reduce flow.What kind of silicone can i use? What kind of paint should i use? Any advice is greatly appreciated.

umm great concept but not going to work.

The easy stuff first. The durso need to be adjsuted, The water level will be just above the lip of the inverted cap, / adapter. Taht makes the water level in your tank really low. right now.

You will not be able to secure the rubbermaid to the tank. You will need to put some glass walls around the overflow, then you can laminate the acrylic to the glass walls. The silicone will not withstand the pressure on teh plastic without having the glass behind it.

The profile on the plastic is really large, / deep. You are losing most of the tank to the overflow. How about triming down that profile.

How about running the overflow horizontal to just below the bulkhead.

How about drilling the bottom of the tank to drain water from thier, then just return the water to the bulkheads in the back

You can buy overflow kits, btw, You might want to try glasscages dot com.

There are others that sell the over flow kits too.

good luck.

I agree, I do not see the silicone holding for long on those overflows. and your losing so much room in the tank to those. plus the drainage might be less than what you expect with the plumbing that way.

with the force of the pushing into the plastic with the water difference

boom there it goes

you are going to have to try different heights for the intank
(as stated earlier waterline is just above the intake)

you are going to need to use freshwater to get the height right

If you use some type of cage or strainer you may not need an overflow

just my 2cents

"How about running the overflow horizontal to just below the bulkhead."~~I guess im not too clear on what you mean.


Can i drill the bottom of my 90? I like that idea much better. Sucks that i just wasted 50 dollars in fittings on my tank.
