Easy and affordable test By Eric on 3/24/2017Eric would recommend this product to a friendI really only wanted the pH component of this (wish they had a pH only kit!) but even still, cost effective, fast, and pretty easy to read.
Buy the kit with the syringe By Grace on 8/16/2016Grace wouldn't recommend this product to a friendThe dropper on the Alk is inaccurate and only measures whole numbers. My readings fluctuatate too much, so I'm going back to the other RedSea Pro kit. Red Sea color changing tests are read best is daylight, so I don't care for the PH test either. I do most of my testing at night, and the colors do not match the card well. I prefer th Elos brand for PH.
Affordable Quality By jmar on 8/27/2014jmar would recommend this product to a friendComes with testing reagents for 100 pH tests and 55 kH test, which is pretty decent for the price and quality to Red Sea is known for. The kH test takes a little to get used to, but it becomes easy after a few tests. The first drop doesn't necessary change the water to blue like it is printed on the card.
