Forgive my manners in asking this, (Not trolling), but with all the high end equipment you've been using and selecting for this set up, why the American Marine Pinpoint pH controller?

I've used their pH monitors and Salinity monitors in the past and wasnt impressed with their ability to stay calibrated over a 30 day period. Some of it was admittedly due to the single junction pH probes I was using, vs the newer and better dual junction probes, but still the swing of 8.2 down to 7.2 during a 2 week period was ridiculous.

Have you not seen similar issues?

I would have figured you for an Apex or a GHL Profilux controller kind of guy and it doesnt appear that you are using a controller?

Not knocking you and not trying to be rude, but I noticed these and was just curious.

Obviously you know what you're doing, because your sps are gorgeous and the system in the making is impressive.

Thank you for sharing.
