How are those with hydros testing automatically?

spscrackhead · Mar 11, 2026

Greetings all!
I have committed to the hydros ecosystem and am looking to automate testing. What are others out there using to test? I am mostly concerned with alk but of course others would be nice, just not 100% necessary. I am currently running a large reservoir with a saturated kalk solution hooked up to a doser to keep up with my supplementation. I will setup a ca rx once demand dictates the need.

Thanks in advance!

I use the iV and X10 combination to test alkalinity. I have 4 test a day scheduled. It will also test pH and salinity if you get that probe also. I do those every other hour.

How long have you been running it and how are you liking it? Would you trade for something else if you did it over?

If you are referring to the first Hydros controller I got that in November of 2020. I was using Digital Aquatics but slowly replaced the Digital Aquatics units with Hydros controllers. If you are referring to the iV I have had it since they came out with it and the X10. I am very happy with my Hydros controllers I have. I get the 4 liter bottle of concentrated reagent and mix it with RODI water. It mixes 4 to 1 and after the test the water goes back into the tank. It refills the beaker to keep the probes in water after the test.
