Looking for a bigger tank

[Jhead85]

I currently have a biocube 29..love it no problems what so ever..done a few mods to it to make it better..have plenty of hard and soft corals in it..tank is thriving..I was wondering if there's any bigger tanks like the biocube..kinda don't wanna do a sump cus the tanks on the second floor and just incase I don't wanna flood..so anyone throw some info if like a tank just like a biocube but a little bigger...maybe 50 gallons at the most

Check the Redsea line of AIOs.

Check the Redsea line of AIOs.

I also like the red sea line there a real workhorse but I like the Innovative Marine tanks better they are higher quality IMO.

outside of a custom build AIO, I would agree that the RSM are going to be the only category that will fit your criteria, at least that I personally know about.
