That sump is looking good! The box is just a junction box I've drilled and mounted the pump into. Was actually hard to find one the right size.I bought this one:anks and I look forward to seeing your build! Im leaning towards an Octo Regal 200S atm and was looling at the same reefmat but it wont fit in the S3 sump.
So far I only have one of the Atlas Scientifics large pumps. This is going to be my RO reservoir (internal tank one) top up and water change pump. So i wanted it to be pretty reliable and high volume.

I'm not tied to their sensors just yet but thought they would be more accurate than the cheaper ones you can find. Which PH probe did you buy because i might give that a go?
Have decided to build my own 4-6 head doser with Kamoer KFS pumps. Works out so much cheaper and will be able to add heads when needed. They turn up this week so thatll be the next thing to build!

The ORP is useless, the salinity seems to be iffy, by the pH is very fine after calibration. I am planning to get a double junction pH probe and try it with a that cheap 2-potentiometers board from aliexpress. I don't trust potentiometers, but maybe?
The fit in my sump looks like this:

It is a very tight fit, all glass in the back was removed, plumbing redone, reefmat is 13mm raised so the handle is over the skimmer's muffler. Heaters are under the reefmat. Access to everything is very good, except to the buttons on the reefmat's drive. I would need to remove skimmer's cup to access them. So far I did not need to touch them. The front of the sump is planed for refugium, either dark or light, life will decide. I need to have a 'copepod farm' for a planned pair of Mandarins.
I forgot: Nice work with the pump! What box did you use?
Had plenty of practice with selecting boxs and fitting them out the last couple of weeks.
