Follow the manual of your dosing system.<\/p>\n<p>Does your dosing system need pH 7 and pH 10?

The solutions fit most swimming pool controllers, including Sugar Valley, Hayward, Zodiac, AstralPool, Bayrol, Seko and Kripsol.<\/p>\n<h2>How to use the 60 ml bottles<\/h2>\n<p>The neck of the bottle is wide enough for your pH probe or ORP probe. With one bottle you can calibrate several times, as long as the solution does not become contaminated. For cleaning solution and KCl storage solution, pour some solution into a separate beaker and let the probe soak in it. If your probe has been stored dry, place it overnight in KCl storage solution 3 mol\/l.<\/p>\n<p>Order the buffer solutions for pH probe and ORP probe.
