I had a problem with several pH probes all in a row. Look at the "O" ring that seals the glass bulb to the acrylic housing. Does it look like it may have worked it's way down to were the serrations in the housing let water flow over bulb? Once the "O" ring gets to the serration s...

I think the cap may be too large, it takes time to charge up hence the delay (maybe). I'm thinking of starting with a 1uF and a 100K POT to experiment with. When you dial in the sweet spot you can measure with a multimeter and know exactly what size resistor to buy. Also it sure sounds like there is...

Hi I'm using the TR drivers and the components I'm using for the smoothing are 22kO resistor and 10uF capacitor. It's not perfect. The ramping is kinda slow and not linear. As in if you go from 0-100% with 10% increments the V goes from 0 to 1 to 2 to 2.9, 3.8, 4.7, 5.5, 6.4, 7.3, 8.2, 9.1 etc. Hey...

Hmm, I need another relay block, I want the wifi, and I don't need this expansion module but it would be way cool for my system. I also just spent $600+ on LED's. Man, this is an expensive hobby! I clearly did not think this whole saltwater thing out enough before I jumped in.

How much is the expansion module and is it available now?

Do you by any chance know what values he's using?

Also I was curious if I add another relay box if I would be able to utilize two more additional PWM outlets? Would I be able to do the moon cycles and thunderstorms without the PWM expansion module using my 2-PWM outlets on my current relay box?

I am using TRP LED drivers that do not except the pulse width modulation signal that the Meanwells require. Is there any way for me to control the TRP drivers with the Reef Angel?
