Has anyone ever considered taking a sample of their water to Leslie's to compare the results of their home tests to a computer? I'm mainly thinking to compare hardness and phosphate. Just curious. I'm thinking it'd be a fun experiment.

It's funny you mention that. I work for a local municipal water department and one of my workers shared a TikTok video where someone took a freshly opened bottle of Sam's Club water. They basically told the guy "Don't swim in that, it'll probably kill you!"Don't make any decisions based upon what they tell you. I'm also a member of a pool keeping forum, and pool store testing is only marginally better than those test strips. We adamantly advise every pool owner to purchase their own test kit and perform their own testing.
Pool stores are often staffed by untrained seasonal workers, ie. teens. And they are not diligent about cleaning and calibrating their equipment. Those digital testers may look impressive, but if contaminated and uncalibrated, they are no match for the accuracy of a decent titration test kit.
As an interesting experiment, we often encourage folks to take the same sample to multiple stores and compare the results. It's wild what they come back with. Oh, and they always need to purchase a few hundred dollars worth of chemicals to dump in.
Our method relies upon off the shelf products (such as baking soda to raise alk) and accurate testing, only adding what can be measured and only as required. I keep a 30k inground pool with a saltwater chlorine generator crystal clear year round for around $300 in supplies. For any pool owners here, check it out at www.troublefreepool.com.
Beautiful Pool!!! Love the rockwork. That was very well done.Don't make any decisions based upon what they tell you.

How is it a strange mix? Calcium plus magnesium plus strontium equals hardness. If I know my calcium and my hardness, I have a fairly good idea what my magnesium is unless my strontium is super high."Hardness" is not useful for reefs. It is a strange mix of magnesium and calcium and strontium.

Sorry, I'm not trying to argue I just want to see how Leslie's tests compare to the test strips and my reagent tests, especially since Leslie's is always trying to sell me products for my pool. After watching the TikTok I mentioned about the drinking water they tested, I wasn't planning on putting too much stock in the results, just interested to see what they tell me.
