I was wondering how long in your opinion should a tank last for if its looked after? Ive got a Juwel vision 180 which i love its heavily planted ive got it how i want it and it has regular maintaince etc, the reason I ask is I bought a 2nd hand small tank 7 gal that sprung a leak a few days after setting it up (no fish in it thank goodness) but i made me question my Juwel should it last years or a lifetime? I dont see me ever wanting to go larger so would like to keep the juwel but in time is there any chance the seams could give out eventully or am i worrying over nothing!!
