The test strips are easy to use and give clear color changes. I’ve been using them for three months and they help me keep my pH and KH stable. The kit comes with enough strips for regular weekly checks.
Virginia Wallace –
I found the alkalinity test very reliable. It matches what I see in my tank’s water parameters. The pH test is a bit more sensitive, but still accurate with consistent use.
