Front Of Tank Flexing!!!
 

I ahve a 35g tank that is fairly old (maybe 10 years) and when I looked at it from the right angle the whole front pane was flexing, not much but enough to notice.. should i be worried??

Yes.

I'd be scared to death lol I would think about getting a new tank before yours cracks:) 35g Tank-$50- losing your system on the floor alot more expensive :) goodluck

Glass tank? If it was acrylic, I wouldn't be too concerned. Glass...yikes!

I dont know
 

I have heard that it is normal to have a little bit of a flex in the glass. Pressure pushing outwards.

some deflection can be acceptable. However, if I were you, I'd drop the water level, put a temporary clamp then silicone a brace there (if the front is deflecting, the back probably is too)

So are you saying to to 2 clamps at each end of the tank at the top and like silicone on like a wood brace to hold it at the top like the bottom does.

My old 220 gallon tank flexed alot. Never broke or cracked though but I worried about it happening

My old 125 hagen freshwater flex's a fair bit as well. It came from the factory like that and has worked this long. I definitly keep a close eye on it though. Its also like close to 5/8 glass too.

I had a 42g tank do this to me once. I did not want to take the chance so I went on craigslist and bought a cheap tank to replace it. I think you should do the same..why worry about it?
