Try as I might, I just can't understand the industrys obsession with top fill. It takes a minute to bottom fill the doggy with the added bonus that there's no flood risk to worry about. Every top fill tank I've owned bar the Kayfuns (with their awesome juice flow control) has flooded with top fill to a more or lesser extent.
We have waited a long time for a new version of the Doggy and all they add is top fill, whilst seemingly ignoring all the other little inherent annoyances like the AFC ring, wire traps, plastic tank etc.
Such a disappointment after 2 years and I'll also be skipping this version. Just as well perhaps, as I now have 14x 2k16's
