AquaChek MPS 3-in-1 Spa & Pool Test Strips

Easy to order and delivered promptly.

Why isn’t calcium on the strip? Now I need to purchase a second strip. Will not buy these again.

We've been using these test strips for over 10 years for our 6 person spa in Vermont and two person hot tub in Florida. They give a quick reading and are very easy to use. They seem to be accurate as the pH and total alkalinity values match my other test strips.

These are very disappointing, especially considering that they're made by Hach, whose water sample chemical reagent kits are widely regarded as the best. I only bought these to measure MPS, since I use Cleanwater Blue and non-chlorine shock, and these are about the only test strips I've found that measure MPS. With that said, though, the pH and TA values read significantly lower than my other two reagent kits read. Very disappointingly, the first item listed in the instructions is a warning that the MPS reading ""may be high if chlorine or bromine are present"". So, if you're like 99% of pool or spa owners who use any chlorinating or brominating agent, these will read artificially high. The edges of all of the squares fade almost immediately, and the centers stay a darker color than the perimeter, basically like the reagents on the pads get washed away. The strips themselves are also very narrow, which makes them a bit tricky to grasp. Regarding the MPS tab itself, the color on the strip never matches the printed comparison charts, so they're completely useless for what I purchased them for.

Use these strips to check our hot tub. They work great and are very accurate. Everything I buy from Spa Depot is awesome and get to me much quicker than I ever expect. Thank you all.

We have used this product for years and are very happy with it and SpsDepot

I only use SpaDepot for all of my spa needs: best prices, complete line, great selection, extremely fast service.

These do a great job and are a reasonable price- what more can you want?

Test strips are reliable and easy to use

Does a good job at determining Alk. PH and MP3 levels

I just bought 2 aquachek mps test strips. I had been using another brand, and when I tested all 3 at the same time I got the same reading. Then I found a bottle of aquachek that had expired over a year ago, and surprisingly that one gave the same reading as all 3 new bottles.

I ordered these for checking levels in my spa that I use Nature2 and mps in... work perfectly!

They are perfect for keeping my spa in order. SpaDepot's prices and shipping can't be beat.

Best price in town nobody comes close!

These little pads on the test strips tend to come off, makes these strips worthless and then you've got to get the pad off the bottom of spa. !!!!!!!!!!!!!!!

I always buy my test strips from Spa Depot. They beat everyone else's prices even if I need to pay shipping costs!

Easy to use and just what we needed.

As far as I can tell they work the same as the major brand for a lot less money.

I shock with MPS once a week and strips help me monitor the level and check PH at the same time.

husband really recommended these for hot tubs

We use these products for our hot tub spa maintenance and really have been very happy

I use it to check my MPS, PH and Alkalinity in my hot SPA. Works like a champ! Very reliable.

But even better is the telephone service I get at spa depot to answer my questions and make sure I get what I need.

We use a mineral sanitizer with our hot tub and these test strips are essential to monitor the water

Used to check the ph, alkalinity and oxidizer level of my spa.

These work quite well for the MPS that I use in my spa. Sometimes I will double check the pH with OTO and it's always pretty much right on. The only problem is sometimes comparing the colors is little tricky to decide which one it is, but my water always seems to stay good.

I like to deal with this company as I find the website was easy to use and the price is reasonable.

works good

I like the simplicity of using the test strips to test the primary levels as: MPS, PH, & Alkali.

Excellent products and always arrive quickly.
