I like these Test Strips and this Liquid Test Kit here.

Tip 1 –Always Follow the Instructions
If the kit says “dip”, don’t swirl or swish. If it says, “swirl”, don’t shake.
Tip 2– Take Samples Away from Return Jets / Outlets
Tip 3– Make Sure Your Kit Is Fresh & Uncontaminated
The chemicals used for test strips and liquid kits don’t stay fresh for long. Most only last 12 months, sometimes less. If your test kit isn’t within the used by date, or is more than 1 year old, replace it.
Let’s face it, a few bucks for a new test kit is much better than an ear infection or an algae problem.
Tip 4– Don’t Touch Test Strips or the Water Sample
Touching the end of the test strips, the water sample or the chemicals used in drop test kits could change the readings. Don’t shake the vial using your finger as a lid either.
Your hands have residual chemicals (think soaps, food etc) on them and could affect the results.
Tip 5– Don’t Test Immediately After Adding Chemicals
Besides, pool chemical levels are fairly slow to change anyway. You’re wasting your time testing any sooner than 4-8 hours.
Tip 6–Don’t Wait Too Long to Take the Reading
Follow the kit instructions here. Waiting too long or not long enough for the sample to change colour will give you an incorrect reading.
Tip 7– Take Samples at least 30cm In Depth
If you take a sample from the surface of the water, you’ll get inaccuracies caused by direct sunlight and evaporation.
This is even more of a problem if you have a swimming pool cover. The chemical levels tend to be concentrated near the top.
Tip 8 – Run your Pump for 15-30 mins Before Testing
I know I said 7 tips, but I just thought of another and couldn’t help myself. Running your filter pump before testing will help to circulate the water and mix the chemicals.
Well that’s it. If you follow these 7 8 tips, you’ll be able to accurately test your swimming pool’s water at home.

I really like what you said about water testing. My wife and I recently swam in a pool that had too much chlorine in it and it burned our eyes. We would not want that to happen to anyone else! Checking your water is the safest choice. Thanks again!
Adrian, these tips that you provided look pretty simple to do. Reading through them is giving me an idea of finding the tools to test the water of my Jacuzzi. Would I also need to do a nutritional testing on the pool as well?
