When is it time for a new tank?

[Fish Folk]

For those with a few years of aquarium experience... when do you decide it’s time for a new tank?

We’ve got a few small tanks that we have resiliconed where cracks appeared. We _know_ that’s like... dangerously playing with... water 😂

After a couple years without incident, we’re feeling maybe safer than we should. They’re small tanks... and the repairs were made carefully.

BUT... we have a 29 gal. that we bought used, and were told been up and running for awhile when we bought it. It has a slight “bow” in the front. Got concerns it might pop. 

When do you decide to decommission tanks? What’s your decision process? Feel free to share your horror stories!

I got rid of my 46 bow front when it went unused for a couple years and the silicone felt hard and dry.

I would say if it's a small tank you should just get a bigger one if you have a 29 I would upgrade to a 40 breeder or a 55. If you can't go larger I would go to petco for a dollar per gallon sale and just pick up a new one
