Comments: If your going to invest in a Korallin Ca reactor you have to have this last essential item. It allows your system to function automatically and keeps your PH levels & Ca levels constant and exact. Unless you want to test constantly this is an essential investment. Of course this means you also need to purchase a PH adaptor lid for your setup. For a SPS tank well worth it. Yes, I would recommend this product to my friends.

Comments: Very Easy to calibrate. I use it with my calcium reactor and have had no problems. Setting the range is a little tricky if you are using the automatic selenoid valve Yes, I would recommend this product to my friends.

Comments: Had it running for 2 months without trouble once set up. Seems stable. The instructions however leave a lot be be desired. I still can't figure out what they say, and I really don't want to read the author's philosophy. Got mine set by trial and error...simple instructions are needed. Yes, I would recommend this product to my friends.

Died after 2 years by tankslave

Comments: Mine worked great till last week. Readout is erratic, and cannot be recalibrated despite two new probes. Output plugs should be grounded. (They are three prog, but the unit power cord has no ground). Yes, I would recommend this product to my friends.
