Aquariums: Has anyone used a tank from an actual fish store?

I often wondered about the viability of this when I worked at a pet store. After watching the maintenance guy work on it, I think you’d be hard pressed to find a good reason to do that unless you were breeding or selling fish. The full installation includes a shared filtration system that can break at many points, and it was all connected to the same sump. That meant that when any fish came in diseased and we didn’t catch it, all the tanks had to be treated since they shared the same water. That being said, I would be curious to know what a residential installation of such a system would look like from a logistics standpoint if someone was crazy enough to try.

Yep, i have similar ones in my store. We bought it from another store closing down, i have 3 of them total 29 tanks all on one sump. $750 for all 3 of them.
I did a pretty long post about them a while back but here’s the brake down.
Everything you do for it is expensive. maintenance can be a hassle, you are going to want to know how water flow works, a background in plumbing helps, electrical helps to.
Water treatments or medication again expensive. IDK where you got the number 60gal, cause its closer to 90, and with 2 of them plus the sump its about 200 gallons. so that’s what you are treating.
There’s are no cover inside, fish can jump out, so make sure it has the back slip and side slips that wall off the tanks or you might find a fish on the floor. with the wall slips you might find a fish in another tank some times.

All in all great systems if you can get them cheap and you are a DIY type of guy, otherwise id just buy individual tanks. If you’re not going to run the sump again id just get individual tanks. Its a pain to move, extremely heavy, and getting them leveled and connected can take a few hours alone. you might want 2 or 3 car jacks on hand and some 2x4s. Its not an easy thing to have, but its awesome to have it.
