Calcium Hardness Tablets (tablet count method)
Product Description: Calcium Hardness tablets used for testing the calcium hardness level in pool water.
Quantity: 250 tablets per bottle
Testing Method: These tablets are added one-by-one to a 100ml sample of pool water. The water will then turn from pink to bright purple. The calcium hardness level is then determined by the following formula
Calcium Hardness Level (ppm) = (number of tablets it takes to turn bright purple x 20) - 10

Other Information: You will also need a 100ml dilution tube to perform this test.

Service review

by Cathryn Bartlett on 30/08/2012
Already sent an email expressing how pleased I was with the price and the delivery. I ordered one day and it was there first thing the next, couldn't believe it. The prices are the best we could find so to get top service too what more can you ask for. It was very personal too as I exchanged emails with Chris who came back to me immediately when I asked a question and was very friendly and professional. I would give an A+ rating.
