Help with a Milwaukee sms122 Controler

[tree333]

Hi everyone I would appreciate any tips on setting up my SMS 122 controlerwith my Octopus dual chamber calcium reactor Usually I'm very technical and can figure most instructions out, but the instruction were really vague, and I dont want my aquarium to turn into a science project, I'm new to calcium reactors so I dont want to screw things up, yet at the same time I'm anxious to get it up and running ,So with that said, I have purchased with the controller, 10.01 calibrating solution, and it came with a sachet of 7.01 solution, but everything I'm reading sounds like I also need the 4.01 solution as well.. My next question is how do I manually set the calibration points? also should I purchase the rinsing solution for the probe for calibrating with the 2 or 3 different solutions? Thank you in advance for any advice!!!

You only need to calibrate it with the 7.01 solution. Just stick the probe in the solution and turn the calibration screw on the front until it reads 7.0.

You should have gotten a card in the box that looks like this.

For monitors that do require a 7 and 10 calibration, I usually just swirl the probe in RO water between solutions.

Thanks Mike! yes I did get that card. so using the CAL adjustment screw, while the probe is in the calibrating solution (7.01) adjust the screw to the 7 position, and the then on the black dial located on the center front panel... set that dial at the 7 position as well?

The dial is used to control your CO2 and has nothing to do with calibration. The probe is usually used to measure the pH of your effluent and turn on CO2 when the pH gets to high. The dial tells the controller the target pH. So, if you want your effluent to be at 6.4 then set the dial to 6.4 and, when the pH gets above 6.4, the controller will activate the solenoid on your regulator and the C02 will start flowing.

Remember to plug your solenoid power cord into the controlled outlet.

Does that make sense?

Hi Mike! Yes that makes perfect sense, thats what I thought. I've had it running now for about a little over an hour and the ph has dropped about .4 already. I'm sure it will fluctuate for awhile... I have noticed some air bubbles at the very top of the reactor, probably from the media, should I bleed that out of the system?

I'm not sure. I have a DIY reactor that doesn't recirculate the CO2 so I have to bleed off the air every couple months or the pump will stop circulating. If its just a few air bubbles then you might not need to worry about it.
