It appears to be but I want to know as well.
Can anyone confirm?
I've done a bit of reading on these, going to get a set for my 150 gal I think. They say they are the same as the Coral Box's but with an 18 month warranty (and also some minor improvements, which I would think will work their way into the coral boxs too, but seems like a peace of mind knowing you get the 'latest versions' when getting the RPM)
