Well, RKL finally arrived. This is actually a little exciting moment, as it could be the beginning of automation of this tank. For now, I'll be using it as temperature control and for some timer functions. Here's what came in the package

• power module with 4 outlets (8A 3A 3A 8A), status lights
• temperature probe (connects to the power module directly)
• head unit (2 line backlit LCD display and 5 buttons)
• USB module, cables for firmware upgrade
• users guide, etc

Paid ~$95US (plus shipping, tax, etc) at bulk reef supply, and this is supposed to be very inexpensive considering what it offers - capability of a dual stage temperature controller, digital timer, wave maker, etc.

You can do things like controlling your main lights with temperature monitor such that it would shut off the light if temperature's too hight, etc. However, advanced programming is not possible.

I have it setup to control heaters, and skimmer/return pump in standby mode, which is really a neat feature and let you delay start skimmer/return pump while feeding the fishes/tank.

Here's the pic with the head unit visible (lower left corner) and actinics on.



It was very hot today, and I had my air conditioner turned off. I did not realize my tank's temperature shoot up to 84F !!! Fortunately, everything seemed to be ok.

I realized this only after RKL was installed. Good thing the temperature is now clearly visible all the time, and never thought the effortless temperature monitoring can bring this much relief!

Anyway, I'm very happy with RKL so far. I do plan to add at least PH monitoring in the near future, and possibly moon light control... and maybe replace all timers with another power module.. we'll see
