I have read on NR SoCaliR that this supplier in So Cal is not so prompt with customer service and that the tanks assembled here could benefit from some quality control. I have heard that the silicone seams can be uneven so it is important to check out the tank (if you were here or at your LFS) before you purchase it. I have also heard buyers being told that their tanks were ready, and when they arrived to pick them up, this was not true. I have heard that buyers have experienced missing parts but also got replacements easily.
I bought what I now believe was a knock off. This existence of such may make tracking such issues problematic but I believe all of the above to be true of actual owners. The buyers of the knock offs were happy to have purchased similar tanks at huge discounts.
So I described what I was unhappy about my knock off. Ikea like cam-joints, HDF (better quality MDF), feet that are no more than plastic cups turned upside down, plumbing that needed to be reworked to fit into the system, and a sump of poor design. As I described these issues to two different Cadlight owners they told me that this is how the Cadlights are!
But search for yourself, I really should not be bad mouthing this company. If you pay attention, people usually write to complain not to praise. I have no idea how this compares to the amount of work they do very well with. But I will say, I remember more than a few people recommending another brand over this one.
For me, the tank is like a car, I car most about how it looks. Then you can add your high performance parts like skimmer, lights, and pumps.
