120AGA reef ready with two overflows/returns or calfo overflow?

[n8rad]

I sold some coral to a local reefer at my house last night and we got to talking about my new 120 that im in the process of getting.

He started saying since all the weight of a tank is on the bottom why would you drill holes in it for drain and return? He said that AGA tanks are very nice and built good but his only beef with them is the drilling of the bottom pane of glass.

He went on to say that i should buy a non reef ready AGA 120 tank and build my own calfo/coast to coast overlow system which is on the back.

Ive researched the calfo design and i must say it looks like a sound design, but i dont think i want that much work of building my own, and i really want to know if a commonly drilled bottom tank is worse to have.

Thanks as always people!

I never heard that argument before but I can tell you that all I have ever seen in person are tanks with the bottom drilled.

My 120 has no issues with holes drilled on the bottom and I would hope AGA would know what they were doing before they sold these things. I would trust them building a tank before I would trust me.

Basically I would think it comes down to convenience. Is it more convenient to drill holes and silicone an overflow, or would it be more convenient to buy an already built tank?

If I could do it again, I would go non RR and get the calfo. Those damn AGA overflows are too big and ugly.

The bottom glass is tempered AFTER they drill the holes to strengthen the glass. I really wouldnt worry about the holes. Theres a few of us (thousands) that have used these tanks for years with no problem.

However, take a look at my post from a two months ago. This tank was not drilled whatsoever. It can happen to any tank, drilled or not. http://www.reefcentral.com/forums/showthread.php?s=&threadid=1018434

Another thing, the AGA 120 is one of their strongest tanks. It uses the same thickness glass as the 180 and 210 which are 72" tanks. I have first hand experience with the AGA 120 and it is built like a truck.

Plumb it up and get it going!
