i have asked lots of people for the differences and pros and cons of both units.I decided to email DA and Neptune for their input and their side of the story. Naturally both will claim to be the best. but here is what i found out and lets see what other have to say.
this is the same question i put forward to both manufacturers.
"Hi
i have been using a controller for several yrs now. another brand have come up in several forums online that i write/read on. i use controller to minitor temp, ph of tank,ph of cal reactor, control lights. wavemaking and sump. also have several alarms and checks and balances. ATO system with float switches.
i have a very complex question for you. why should i change over to ur brand?
what is the key difference that you would sell me on to buy this unit?
thanks
Note: i am seriously looking into ur brand but i dont know what i am buying. as
of right now both units look/seem same except for 2 different names."
this is the responce i got from DA (with in few mins)
Never heard anything from them yet after this autogenerated email.
Thank you for your message. We have received it and will get back to you as soon as possible.

There really is no comparison between the Apex and the RKE; the Apex
surpasses the REK in just about every aspect. Here is a list:
- High Quality Display with excellent clarity/contrast.
- Costs less.
- Easy to use configuration wizards.
- Most expandable controller - up to 240 modules, thousands of outlets,
hundreds of probes.
- backwards compatible with older AquaController accessories.
- More features - Some include:
more flexible/sophisticated configuration
season lighting control
season temperature control
- Integrated Ethernet (Optional $$$ on RKE)
- Only controller with monitoring & Control & configuration on the webserver
- Monitoring only on RKE with optional Ethernet attachment.
- Only controller with web browser based configuration.
- XML support
- multiple head unit displays with full user interface - not possible on RKE
- multiple sound alarms.
- Includes 6 digital inputs vs 2 on RKE.
- Galvanic Isolation on probes result in accurate readings. RKE has no
isolation and has major interference issues.
- Includes built-in variable speed pump control. Not possible on RKE
- Optional support for Ecotech Marine's Vortech pumps with WXM module. Not
possible on RKE
- Includes built-in 0-10V light dimming. Extra on RKE
- Can name outlets, and modules - not possible on RKE
- ORP input is modal - can be ORP or pH input on the Apex - not possible on
RKE
- Default outlet state on Apex. On RKE when a communication error occurs all
outlets just shut off
- State of the Art 32 bit processor - not an 8 bit slow processor like RKE.
- 5 times faster than competitor's controllers
- 16 times more code space - much more expandable for future enhancements.
Not code space limited like the RKE
- 16 times more storage space for datalogs than the RKE. Up to 1 years worth
of data can be saved in the Apex
- Bus interconnect can be starred or daisy chain configuration.
- Apex base unit has power failure detection/alarms/control - not possible
on RKE.
- EB8 has power failure detection/alarms/control - not possible on RKE
- Don't have to disassemble controller to perform firmware upgrades like on
the RKE
- Reliable/High Quality buttons (No unreliable capsense)
- Lowest cost per outlet control options
- Robust communications protocol Bus Interface with error correcting. RKE
uses I2C and has communications issues.
- EnergyBars have built-in AquaBus hubs - On RKE must purchase add-on.
- Auto setting of clock from internet - not possible on RKE
- Day light savings time support - not possible on RKE
- Built in virtual outlets on Apex. On RKE must purchase a PC1 for virtual
outlets.
- Cable lengths can be much longer than RKE.
