Review on Tetra Correct PH Tablets 8 Count by Karen Mabey

This is the main product in my aquarium care box. They're easy to use - I break them in half and fill a bucket with a black mark at the 5 gallon mark. I add half of the water conditioner (measure 1 strand of the cap) and stir a little. Then do a quick water change - this is for maintenance only - it's a lot easier than testing with ph + or - powder and then testing. Trust me - it's great.
