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 Nigel Morris on 31/05/2013
I have always rated your service which is why I keep coming back. Having said that - the inflatable dolphin has a leaking fin straight out of the box - only blew it up yesterday - can I have a replacement please.
Swimming Pool Chemicals response : Very sorry about this Nigel. We will get a new one sent out today.
