    • Be careful what fish you put into a community..
Size: 55 Gal
It came over perfectly!! It's amazing!! I love it, I set a whole ahh community tank with loads of beautiful fish in them. It was worth it. It's easy to clean and care for (since I got corydoras and a filter) easy to use (adding this cus check mark, at this point I'm blubbering, it's a good ass tank) and no leakage! And it fits everything! (I can't check mark the ideas area noooo). ... show more

Delivered on icy driveway. It unpacked in minutes and was set up within an hour. Great job! We lost power for a week and all the fish died. Then the old tank leaked out several gallons onto the carpet. Now we need fish.

    • Oooh La-La!
Size: 29 Gallons
I've wanted to have an aquarium since I was a kid. This is much taller than I envisioned to be, I can see that may be why the specific unit I bought was a used/return - I'll take a deal price like that every time. The one complaint I can lodge is the sticker stuck fast to the bottom inside, it'll be a nuisance to remove. Besides the discount price, the 18-inch height was one of the main reasons for choosing this one, more viewing area and a taller water column generally, for more potential activity. It's really not as heavy as one may think, but it is a touch awkward to handle given the dimensions. This is a relatively large volume of water, so it'll be heavy - one must account for that. I'm setting up a multi tank system with this as the main body, a 7 and this as 28 make a solid 35 gallon to work with. This is tempered glass, so it has the extra strength to actually support the weight of a small(er) tank sitting on top; although I'm pretty sure it'd hold up to it, I'll be fashioning a stand of sorts to help augment for strength of structural integrity. Describing it isn't much help, I know, so I'll add some pics to this review once I get it up and humming. This tank came with a couple packages of tank treatment 'stuff', which is at least a clue/notifier of the need to treat tap water, if not on a well - which I am. This is just a tank without any components, not a kit - although that is clear on the page data. The 2 "main" differences in tanks are the rim/rimless configuration; I'm adding a negative pressure tank, or 2, also - but both of mine have rims that will need modified to accommodate it/them - I want at least 1 on each tank. If my modification works, I'll definitely share it and include in this review as an edit. Besides just getting to finally take up a hobby of great interest, I'm also hoping this may become a potential "side hustle" of sorts, there's some species of fish and invertebrates I want to breed also; this tank has sewn seed for lot more than just this one. ... show more

    • Damn expensive for just a tank

Bought this for $250 when I could have went to the pet store and got a complete kit for the same price but I already have a tank set up and I just needed to swap the tank.

    • Great product.
Size: 29 Gallons
Great quality, came well-packaged with little Tetra freebies. (Guess that's why they call it a "kit"?) Purchased for a brooder and it worked fine.
