Can Someone Explain This??

[mrtint]

Been looking for a 200-300 gallon tank for some time. Came across a 220 for sale not far from me. Went to see and the overflow makes no sense. Let me see if I can explain
Peninsula Tank 72"x24"x30"
Strange part is the overflow. It is at one end has 3 holes drilled in bottom of glass tank but holes are 6" 12" 18" from end of tank right down the center. So the overflow box is basically 6"x24"x30"tall. So when you view the tank from the side it looks like a 4' tank. The overflow box only leaves 9" between box and glass on each side.
Can this be fixed? I could plug the holes but plan on filling with rock for reef. Will it hold?
Its just driving me crazy as to why they drilled the holes there to begin with?
It was purchased that way from current owner so he cant explain. The only thing that might make sense is the first hole may have been the original overflow and the 2 other holes were part of a closed loop?
Anyone have a suggestion on how to fix? I would like to plum thru bottom and do a Herbie set up in overflow box But am willing to do external overflow. I kind of think just sealing holes with bulkheads and starting over with external setup is the safest and easiest way to fix. just dont think I should be drilling new holes in the bottom with 3 already plugged. I could also seal the holes with a glass patch that would run edge to edge if that would add strength to bottom instead of bulkheads.

Just use silicone and put glass over the holes inside the aquarium.

You will put a fair chunk of time, money and effort into creating your system, and will looking at it almost every day. This overflow may have suited someone at some time, but I think you should keep looking. You don't want to have regrets when you are done.

^ what he said.

You are going to put a ton of time/money/effort into this... I'd wait and get exactly what I want. Even if it meant saving for another 6 months to buy the tank new or whatever... I'd just wait.

I got my 75 dirt cheap (150 for tank and stand) but it had one of those stupid giant Marineland internal overflows thats off center. I ripped it out and patched the bottom with a piece of glass like what was suggested, but even with rock hiding it (bare bottom, ugh) its still a pain to design around. If I had to do it again I'd save up a few more bucks and do it properly. Aka, new, or at least exactly what I wanted.

If the deal is good enough and you will have a sand bed, I say silicone and glass over the holes. Remove the overflow and build an internal coast to coast with the plumbing external.

I agree. Been looking for 6 months for right tank. I can by new..... Just have seen a lot of tanks go for cheap in the pass. My main draw to this tank is NOT the tank. The guy is moving and is desperate to sell. The live stock alone is double what he is asking. 1/2 the equipment is quality the other half is junk. If I can find a place to keep livestock. I may buy just for equipment and live stock.

Thanks everyone. Your right. I'll wait for right tank

Tank may have been set into the wall with only the 4' section showing.

Having a long narrow overflow like that also increases surface skimmer area vs a traditional overflow design.

How big are the drains? Maybe they are 1 1/2" and there is no room to stack them closer?

Provide diagram. Sounds like a closed loop system.
