Accurate to a point, easy to install, transparent housing.
This Ph monitor began working within 30m just as advertised. It's also congruent with my test strips, so I would trust it's accuracy, although it's no replacment for a master test kit with additives. Would buy again!

Is accurate and works quickly
I use this with an api test for ph and when adding ph within 5 minute the ph alert changes colors and matches exactly with perhaps a slight difference of at least .5 if at all but I trust Seachem products all the way as someone with every test kit and cares deeply about the quality of my aquarium.

Inaccurate readings after a week or so in 55 gallon tank
First reading spot on, but after some time (within next week or so) readings are very inaccurate - either way too low or way too high when compared to other measurements methods ( API master kit or pH paper). Most likely my first and last purchase. I’m not sure if this has anything to do it, but my tank is 55 gallons and has some agitation from air stones and filter.

Amazing
Lost some fish and I couldn’t figure out why till I got this. To top it off I don’t have to test the water with strips all the time. A simple visible always on indicator is exactly what I needed

Take a Day to Calibrate...
It took a day, but finally calibrated.

Works in minutes and is very accurate!
Works great! Had a proper reading within minutes. Verified with chemical test to provide its initial accuracy and it was dead on. Will keep in all my tanks!

So far so good :)
Seems to be working as it should. I'm happy to have this in my aquarium & know my fish will be to. Will follow up if stops working correctly.
