How many times can you test your water with this kit? Can you order individual refills or would you need to buy a new kit?
Benjamin Lewis on Oct 4, 2021
BEST ANSWER: I haven't made much of a dent but have only done 5 or 6 tests. There are 50 of each tablet (calcium hardness indicator, hardness reagent, and sulfate turbidity) so my guess is that's what you'd run out of first. Some of the liquids are much larger than others but all should be enough for > 50 tests.
does the product (or its components) have an expiration date?
denis ticona on Aug 22, 2019
BEST ANSWER: Hello Denis, yes each reagent will be marked with their own expiration date.

Excellent self test if pretty close is good enough
I ordered a Ward Labs report on my water and while waiting I decided to perform a self test using this kit. The process is as painless as can be expected (similar to testing chlorine in a pool) and there are very good instructions on how to complete the test. The results were comparable to the professional lab test; although, the lab test was more precise. If you have low ion concentration in your water then a difference in one extra drop can mean a 50% difference in hardness values…for brewing this is likely ok. It’s also ok if you have a high ion concentration….say hardness of 220. A difference between 220 and 227 shouldn’t be a big deal, but a difference of 10 and 14 might be. The thing the professional test gives you is precision if it’s important. The thing this test gives you is repeatability. Since water quality changes over time, it’s important to monitor every so often and that would be very costly with professional testing.

Better Beers through chemistry.
I've been really enjoying my LaMotte water testing kit. I've had a lot of fun testing my own water and friends and relatives as well.I knew that I had hard well water, but I had no idea just how hard it was! My first two brews were entirely with my well water. The ales were certainly drinkable but despite being heavy with hops I got no bitterness and hardly any hop flavors because I had zero sulfates in my water.
There is a mountain spring 15 minutes drive from my home so I've been getting all my brewing water there. The water is so pure that it's almost like RO water. I've been using Palmers Brew water app and adding salts and acids to make the perfect water for my ales. What a difference it made!
I heartily recommend this test kit. It made a world of difference in the quality of the ales I'm brewing.

Great tool for serious brewers
Any serious brewer should be concerned with their water chemistry. The results closely match a Ward water report from 1 year ago, so I'm confident in the accuracy. Great kit.

Getting ready for all grain
I have used the kit once so far to establish my water composition. It was easy to do and gives me confidence about adjustments necessary for my first all grain batch.

Great kit
I had no idea where my water Ions were for different styles of beer other than the annual local water report that was not even close to where my actual test results were. Not to mention the local water report was not taking into consideration what it would be after the carbon chlorine filters I had installed. Plugging the test results of the actual water used into beer smith has allowed me to hit the water for the style I am brewing easily. Highly recommend this.

Easy to use, matches professional testing
I've been sending water samples out for testing for the past few years, but figured I'd try to dial in my water more accurately by testing it before each brew. Got the kit, did all the tests in under half an hour (and I expect that to be much faster next time now that I know what I'm doing), and the results were pretty close to the Ward Lab test I'd got a few months ago. While it doesn't have the same level of accuracy as say a Ward Lab report (10ppm steps are the smallest in some cases, where Ward Lab will get to 1ppm), this is easily 'good enough' for making homebrew. And considering how many tests I can get out of: Easily worth the money.

Easy to use, plenty of material for many tests
Without data it is just an opinion.This kit will get you the data you need in reasonable ranges to take your beer to the next level without breaking the bank. If you want to brew beer better than you can buy, this is a good investment.
