RKE fully loaded with net module is 350 otd
The apex gold is 800...
How is that not much more money? What am I missing here.
That is not a fair comparison.
The standard Apex package is $525 on BulkReefSupply, the RKE is $350.
The Apex comes with standard features that would require extra modules o the RKE. The Apex has internet connectivity, but you would need the RKE NET at a cost of $450(from other sites, cannot find on BRS).
Also, out of box the Apex has 4 dimmable channels for control of LEDs and Tunze pumps. The RKE requires an additional module that runs about $130.
I have owned both systems, and have been highly critical of ReefKeeper. But that was quite a few years ago. Most of my issues with them centered around delays in correcting problematic modules and slow customer service. I have no idea if they have improved since, I hope they have. I think for a while they stopped going through dealers? But they seem to now again.
I did like the display much more on the RKE than the APex, namely for changing colors. The power strips were also 4 outlets times 2 for the package, but each strip had 2 mechanical relays as opposed to 2 mechanical relays on the 8 outlet one included with the Apex package. Just being able to use different circuits it is nice having 2 strips. Please take the post with a grain of salt

, it has been years since I knew the details of both very well....but I did check before I posted.
