Well what do we have here? Seems Digital Aquatics has been busy working on bug fixes for the Reef Keeper Elite, thats not all though. Their new PH probe has been released which will replace the standard probe that was bundled with their Reef Keeper controllers. The new probe which has a resolution of 0.01 pH comes with the necessary calibration packets that you’ve come to expect in a standard PH probe. Like most other PH probes on the market it uses a male BNC connection to communicate with your controller. The price for all of this? $37. Now say that isn’t beyond reasonable, we will take two please.
