GOOD KIT
I was using a Fluval test kit previously, which required placement of drops from 3 different bottles in a tube of water.However, since the number of drops from each bottle was different, one tended to run out before the rest.As my local Petco didn’t have this kit in stock, nor was it available at their on line site, I looked for it here, and it is listed.I saw this one though, too, and decided to try it, as it looked much less labor-intensive, which it is.It’s really easy, seems accurate, and doesn’t have the inequities between the varying fluids the Fluval has.I like it, and will be using it exclusively in the future.

Good for the price. Easy to use.
I found that the product worked well. I went to my local pool place, and they gave me a reading of 800 for the phosphates.The strips worked fine. There was maybe 7 different examples for checking the color. In the end, it was not on the low side……….and it was not in the middle………..it WAS more to the high side, which BTW, was around that same 800…. possibly 1000.It’s tough to use the strips and try and EXACTLY match a color. So, my take is to just eliminate – no, it is not on the low side………….no, it is not in the middle…………yup, it is more like the high side.That works for me, for sure. If you are looking for an exact number, then go to the local store. BUT, do keep in mind that it is in THEIR best interest to show you a HIGH number, so you buy more Phos Free product! AND, i must say it cost 2x the cost from Amazon for the chemical.I almost deducted a star due to the expire date of December 2023, and here we are in June 2023. And, it was manufactured in 2021.But, it did work fine……Overall, I would buy again.Update 06/06/2023: Customer service reached out to me, with apologies for the stale date package. They shipped me a full replacement!!! Wow, THAT is true customer service. THANK you!!! Can’t give them more than 5 stars!!! ha.

Excellent phosphorus reading
Reads phosphorus levels in water. Easy to use. High Phosphorus levels in pools increases algae growth. Keep it low. Test a few times a year. Especially after large rain storms.

They seem accurate?
So I’m using this for saltwater, and while they seem to be pretty accurate, my only gripe is the way in which you read the results. You do not read the results in the strip itself, but rather use the water that is in the test tube after you shake the strip in it. It is very similar to how you read phosphates with other test kits where you use a color comparator. This was a disappointment as I thought these were traditional test strips. This may just be a limitation to how phosphate testing is done overall however and not something specific to this manufacturer. In the end, the strips do still use less water to measure and have the benefit of not needing to count drops or mix some potion before measuring.

Product worth the money!
I recently purchased these for my reef tank as my corals seemed to not be doing so good. Ater testing my water with these test strips they showed my tank had high phophate levels. Thanks to these test strips I was able to save my corals. Highly recommend these for anyone that needs to test for phosphate as they are very accurate and easy to use.

NOT FOR A SALT WATER HOT TUB!!!!!!!!!!
I used these test strips as it is instructed for my salt water hot tub. It always read that the phosphate level was low. I got a second brand of phosphate test strips (Freshwater Phosphate test strips) that the hot tub repair man used & recommended. The reading with the Freshwater strips were TOTALLY different and showed the phosphate level topping out at 2500 (dark blue) = very high phosphate level. So these strips are VERY inaccurate because the phosphate count was TONS higher than it read on this brand but showed a low level… They’re completely inaccurate for a hot tub. We threw them right in the trash. Total waste of money for the hot tub.

Easy to use kit!
This kit comes with 2 vials for collecting water sample and a lamented comparison chart to check the level of phosphate in pool water. The 100 test strips stored clean and dry inside of a plastic bottle with lid. Seems to be accurate test for what I am using it for.

Great price! Useful for spas and hot tubs too!
These test strips are half the price of the ones marketed for hot tubs, so whether you have a fish tank, pool, or hot tub this product is a great value. The test strips are just as accurate, and most multi-purpose test strips for pools and spas do not include a phosphate test. If you use a salt water chlorination system, the first thing you need to measure and balance is the phosphate level of the water, but startup kits only give you 2 test strips. This product is what you need.
