ell I ended up buying it already. I was able to get it for 475 for the tank, stand, lights, heaters, 2 fx5 canister. In person it didn't look too bad. There wasnt any bubble on the seams. I know every tank varies and but how much time do you think the tank may have yet? From your estimate
F Fishyboi4 acrylic tanks can last 30+ yrs if it was well cared for. That meant tank should be store indoor away from the sun or extreme cold. Tank should sit flat on well support stand with plywood top. This assuming the tank was build correctly at the manufacturers. I have some old acrylic tanks that are 20+ yrs old and the seams still looks solid.
That’s not a bad price you paid with all the accessories. From your pictures I would say that 180g is about 8-12 yrs old.
