How much bow is too much bow? 29g aqueon add a brace?

I finally just got around to doing a leak test and while filling the tank on the stand and the hood on I heard the sound of the frame shifting under the hoods weight. I noticed a small amount of bow, probably much less than what other people experience, I'm just very concerned as this will be on a second floor and don't want to end up replacing a ceiling.
What harm or good could come it I was to make a brace from a 1x2 notched to fit exactly on the frame when empty to help hold and brace it?

I can't judge necessity but anything you do that stops the sides from spreading would work fine including a 1 x 2. You want to make sure that whatever you use is installed well enough to hold. If you installed something that 'suddenly' broke loose the outward pressure at that moment would be a lot worse than the slow bending you are experiencing now

You could also silicone a Lexan/plastic brace across the top glass to glass

That said, I think a small amount of bowing is standard

Silicone doesn't adhere well to plastics. If you're worried about bowing use a piece of glass instead. at one time Oceanic tanks did that on the larger tanks.

Dilution is the solution for the pollution.

Don't they put spanners on acrylic tanks?

Glass is no doubt better but having a thicker pieces of glass cut with smooth edges is expensive and people are afraid of it.

EDIT: I think acrylic tanks are glued...my bad

How much could a 3" x 12" piece of 5/16" glass cost?

Probably $25.It would take a minimum of 3/16" and hardware stores only go up to 1/8". It's not the cost of the glass, it's the labor of cutting it and smoothing the edges. Most glass shops have minimums because it's difficult to make any profit on small jobs.

When people call me to repair one window I cringe, I don't do it for profit because there is none, I do it for the goodwill...everybody knows somebody.

But there's no steadfast rule, there's lots of small town glass shops with amiable owners who may even do it for next to nothing, especially if he/she likes aquariums. You never know till you ask. I do free repairs all the time especially for the elderly because I'm right outside that door trying not to knock.

this is a typical glass tank with plastic trim to clear up any confusion.

There is no confusion Chris. Graphics was right that a glass crossbar is the strongest fix. The glass piece which would be about 6" wide would go at the very top inside the tank and would be silicone d to the front and back glass and clamped overnight.

However, I've read a lot of posts about minor bowing and the general consensus is that it's normal. Aqueon makes a good tank, unless your tank is bowing more than normal I wouldn't worry.

Why not run a straight edge across the front and measure the bow so that some folks with Aqueon tanks can grade whether it's normal or bad.

Acrylic tanks need to be either full top braced or strips in a euro style bracing manner. Actually acrylic is stronger than glass. 17x stronger. The problem as stated before, silicone doesn't adhere well to it. In a sump you can get away with it for baffles though.

Also acrylic tanks are molecular bonds not glued. Its a reaction in which the acrylic melts and fuses itself. This makes the tank seamless and virtually leak proof.

To the O.P. if it were me, I'd go with the glass bracing vs the wood bracing. If you need glass, go buy a tank from the $1 sale and break the tank down. Its not too difficult to do if your patient. I bought (2) tanks just for the glass. Get a good glass cutter though. I didn't at first and ended up wasting (1) tank. To get a reference on price, I needed to make(8) c2c overflows for my current project. I needed (8) 4.5x35 and (8) 2.5x35 at 1/4" thickness and that ran me $158. $1 glass is much cheaper and you get alot of it as long as you don't need anything over 3/16".

would 4" wide jalousie glass be enough for a brace from front to back? its 1/4" thick. i measured the total displacement at 3/16" which is just over 1/16 each side.

Perfect, as long as it's not tempered, great idea as it has rounded edges

Buy a decent glass cutter $7 (real cheap ones hardly work) Cut to length and use a sanding block to smooth the cut, silicone and bar clamp overnight

Best if you have enough to experiment with

PS: blocks of wood between glass and bar clamps and do not overtighten, snug is good

You don't even need bar clamps. Packaging tape works wonders. No. I did not say duck tape.
