Very Scary! Tank Creaking after water change!!!

Has anyone experienced your tank creaking after a water change? I am very concerned that the whole thing may crack! I have plugged and unplugged all equipment and I am pretty sure the actual tank is making the noise.

Mine creaked the first couple of times I filled it up with water. I thought at the time it was just the stand settling - but never had it since. Did sound like glass creaking.

How old is the tank? Any chips or silicone pealing off anywhere? Can you see any air trapped in the silicone (that is a sure sign your joint is going to blow out).

Perhaps keep a roll of duct-tape nearby in case you need to hold the glass together! (It would actually be strong enough).

As I move house quite a lot (every 1-2 years) and I always measure the length and width of the tank dry and then fill the tank and measure again - I figured if I had damaged the joints they would show when measured full up with water as a tad longer/wider.

Thanks for the quick reply.

The tank is more than five years old (probably older but I'm not 100% sure because I bought it from someone on craigslist). I have had it for a year and it has held water fine. There is algae growing under some of the silicone, but I don't see any air bubbles. Perhaps it is time to buy a new tank.

Did not mean to make you buy another tank! I am sure it is fine - just keep a close eye on it for any further creaking. I can understand a new tank creaking/settling but not an old one.

Just inspect it as best you can and if the creaking continues that could indicate a problem.

Only about 10% of burst tanks show no signs of damage prior to them popping their joints - the rest are VERY obvious: bubbles trapped in the silicone, flaking silicone, expanding joints etc.

Mine creaks on every water change. I bought it brand new and it's been set up for like a month. I just assume it's fine since there's no noticeable damage, but who knows.

I always reseal used tanks before refilling them. Dry rot can do a lot of damage to silicone quickly, if the person you bought it off had it dry for several months it saps the silicone's elasticity.

resealing is as simple as cutting out the old silicone with a razorblade (preferably one with a handle) using a brass bristle brush to clean up whats left, wiping the corners down with rubbing alcohol to get any oil residue from your fingers off the corners then running a bead on all 8 corners. smoothing the silicone out. letting it dry for a minimum of 24 hours. Then finally trimming away any excess squeeze out from smoothing.

another possible cause for creaking when filling (especially in old tanks) is grit, dust mini gravel chunks etc stuck in between the plastic framework and the glass, so that as the tank settles when filling the glass and the plastic move in relation to each other causing the grit etc To rub and make noise.

I would also recommend double checking to make sure all four corners of your tank, as well as front and back center are touching the stand when the tank is empty. if there are gaps at any of those 6 locations your more likely to get, noises and excess tank flexing. (it also puts more stress on the siliconed seams to flex a tank like that.)

Just a thought - Is your tank fairly well leveled ? Have you ever checked that out?
Even if you've had it up for a year, perhaps the constant stress from a non-level tank will cause things to weaken over time, and begin to creak ?
