There have been three releases of tis aquarium (according to the reefer sites). Which means there were lots of problems. Who knows, perhaps they are fine.
They are much cheaper than the traditional systems that are most popular for SW. Which always makes me a bit nervous.
I'd pay a bit more and try waterbox or a tank from glasscages. I upgraded last year and looked at them and they weren't available - I think for the upgrade. I went wit an acrylic as I wanted a higher height dimension
In my mind, they have not been proven.
