CYA Tests – Testing Tips!

A client recently had an excellent question, they wondered if we had any photos that demonstrate the disappearing logo in our CYA tests. So now, we do! They wanted a better idea of when exactly the dot has disappeared versus just being hard to see. The CYA test is incredibly subjective and also can be […]

Reagent Lines and the Curvy Meniscus

Meniscus Article

The first time you use your kit you’ll probably notice that the pool water curves upwards at the inside edge of the tube, and doesn’t sit perfectly flat on the reagent line. This curve is called the meniscus and in this article I’ll explain what the meniscus is and why it’s important for pool testing. […]

How to test for Salt using a Hydrometer

Hydrometer Cylinder and Samples

Unless your pool has a salt water generator (SWG), it is unnecessary to test for salt levels in your pool. SWGs consume the salt in the pool to turn into free chlorine, meaning that daily addition of chlorine is unnecessary. Most SWGs have a broad range of operation (the difference between the “too little salt” […]

How to test for pH levels

pH is one of the critical elements that your pool maintenance program needs to get right. Too far towards either the acidic or basic ends of the pH spectrum could cause both swimmer discomfort and damage to the pool. The instructions on the sides of our kits are simplified reminders of the procedure for advanced users (see […]

How to test for Calcium Hardness (CH)

Water that has low Calcium Hardness (CH) tends to attack most pool surfaces (except vinyl pools). However, too much calcium leads to excessive scaling which can clog pipes and render salt-water generators inoperable. Therefore maintaining a balance of calcium is critically important to the long term maintenance of your pool. The instructions on the sides of […]

How to test for Total Alkalinity (TA)

Measuring the level of Total Alkalinity (TA) in your pool gives you a way to understand how susceptible your pool is to wild changes in pH. Low levels of TA will mean that the pH in your pool will be unstable. However, high levels of TA will also make it hard to maintain optimum pH, […]

How to test for Cyanuric Acid (CYA) levels

Whether you call it cyanuric acid, stabilizer, or sunscreen for your pool, CYA is one of the critical elements that help keep your pool clear and healthy. UV light (which Australia has in over-abundance) causes the depletion of free chlorine. Without CYA, you have to add more chlorine to keep your pool healthy, or run your salt-water […]

How to test for Chlorine levels

Separate testing for free chlorine and combined chloramines (together making total chlorine) not only helps you maintain a healthy pool, it helps you control your chemical costs by making sure you add only what your pool actually requires. These are the extended instructions for the FAS-DPD 3 in 1 Kits, that give you all the details […]
