Eagle Ray Digital Water Testing Kit for Spa & Pool - Digital Hot Tub Water Tester by AquaDoc with Analyzer & Hot Tub Test Strips for Chlorine, Bromine, Total Hardness, pH and More

My husband and I are first time pool owners. We have a 40’x20’ in ground pool to maintain. We had a pool guy come out twice and that became way too costly so I knew with the right tools my husband could maintain this (and there is always Google for resources lol lol). I started with this amazing test kit. It made my husband’s life so stress free. The water testing was very easy and fast, perfect for my husband. It is very accurate and allows him to add the right amount of chemicals to keep our pool crystal clear. No guess work. Highly recommend this test kit

Seems accurate, which I think is the most important. I compared the results three times with a pH pen, another brand of strips, and a liquid indicator kit. Definitely more accurate than the cheap kits. I think it’s easy and fast. The only value that changed every time (I didn’t do anything in between reads) was the Total Hardness (TH). So not sure what to think about that, but it fluctuates about 30 ppm each read.

Easy to use, accuracy was questionable. As an example, I took two readings from the exact same sample of water and had two wildly different readings. Example: hardness 352 & 500, pH 6.8 & 7.4. If there's a calibration method I have not been able to find it. *Update* I want to add on to this review by sharing that the customer service is outstanding. The team reached out to me, ran me through some tests, and agreed that the unit should be replaced. They sent a new one out immediately and it seems to be reporting more consistently. It's important that this vendor stands behind their product, and I appreciate that.

Once you learn how to use this, it’s pretty awesome. So far so good. Had to get a hold of Customer Service because I really couldn’t figure this out. It goes by numbers instead of trying to figure out colors so that makes it a whole lot better. Has a function that you can take a reading put it in the machine the machine evaluates and then you’re able to press the button that allows you to take a picture of the results and send them into the company which immediately sends recommendations on what you need to do. So far it’s worked very well. I would definitely say worth the money.

If you're using these for a spa and you don't understand how all the chemicals work with each other, this can be confusing. While it's an afforable soulution, it takes some training to fulling understand how to adjust levels. Watching a youTube video on how these work is worth your time. These are high quality, accurate, colors are clear, and the clorine levels are exact.

Works hreat. I am colorblind so reading a test strip by color is impossible but the digital read out lets me balance the pool water with a digital readout, not by comaring test strip colors

Unfortunately stop working after few months. Cleaned product white deflector as described in directions. I know it’s unit because multiple test strips from other brands all line up. I Contacted company and we decided could be bad test strips so they sent new ones. However it did not correct issue and now Amazon will not allow you to contact company or ask questions to actual person. To good to be true and was excited if this read light levels properly as described. No good , stick with the good old fashion test strips. I also have other expensive water analyzer as well and it worked temporary as well…

I have a large vinyl saltwater pool, and have tried various devices to monitor the water chemistry over the past 20+ years. The truth is, to some extent, you get what you pay for, and sadly, most of these don’t work very well. I will review the Aqua Doc, Taylor test kits, AquaChek Trutest, and Accublue (Leslie’s). 1. Aqua Doc - I really wanted to like this device. It is expensive at just shy of $200. Interestingly, it is no longer showing as for sale on Amazon or on Amazon’s web page for their store. The strips are still available. Not sure if that means it’s out of stock or is no longer on the market??? On the plus side, really nice case, though the standard 100 count test strip refill doesn’t fit in it. Really? Tests are relatively quick and easy to perform, and the strips only work out to about 12 cents each. Consistency of readings was good. If you ran 2 or 3 consecutive tests on the same sample, the readings were quite similar. The major downside is accuracy. At first, I used the small vial of included test strips. This had no type of foil seal, and ph consistently read about 6.5-6.7, when the actual professional reading was around 7.6-7.8. Likewise, free chlorine consistently registered about 1.0-1.5 ppm above the the reading , that’s 1.0-1.5, not 0.1-0.15, so when the pool was 2.1, it read 3.4. CYA was also off, about 20 above actual. And so on… Hence, the 2 star rating. I will be returning it. 2. Taylor kits (various) - Reasonably priced. Cumbersome. Most tests must be run separately. For example, Alkalinity requires filling a tube to a certain level. Then adding three different sets of drops, the last being a one drop at a time affair, swirling and checking for a color change. So if you need a full analysis (multiple chemistries), it’s going to take awhile. As to accuracy, if you’re familiar with these types of kits, you know that trying to discern by eye the difference in color between a ph of, say 7 and 7.5, is pretty much impossible. Too much time to just get a general ballpark idea where you’re at. Not recommended. 3. AquaChek Trutest - This small blue digital meter reads ph, chlorine, and alkalinity. Quick and simple to use. Gives a digital readout. Decent accuracy. Used this for many years. Occasionally got bad (error prone) refill strips. Consistency poor, often requiring several strips. I believe this is no longer made/unavailable. 4. Sutro - Very expensive. ?around $500 for device and $40/month subscription. Measures ph, alkalinity, and choline 3 times per day. Device stays in pool. Readings transmitted via WiFi to phone app. You swap out battery and new cartridge once a month. Sounds great. Right? ph and chlorine generally within a few tenths of a point. Alkalinity less reliable and actually only measured once per day, other readings showing a range. Lots of problems with occasional defective cartridges, slow shipping (greater than a week to east coast). On the plus side, when it’s working, knowing chlorine 3 times per day, is invaluable for making sure your SWG is working properly. It does not take long for algae to start when chlorination fails- great if you’re out of town and want to check remotely. But you’re paying a steep price for that functionality. 5. Accublue - This is Leslie’s subscription product. On the plus side, it is the most accurate of the various options I have used. Not cheap. $50/month, no included test disks and those are expensive at $9 for a 5-pack. So if you test daily, a month of readings is $54. You do get a $50/month credit for anything they sell (chemicals, the test disks, etc.). You can only pause the membership fees for 6 months per year, so if your pool season is May-September, you pay for an extra month you stint need. Also, their online delivery (test disks, chemicals, etc.) is quite quick (couple days) and you can also use the monthly credit in store as well. Probably your best value if you only need to test infrequently, say once per week, want the most accurate readings, and can benefit from $50/month worth of chemicals. In summary, there are a lot of options out there, with various pros and cons and a wide range of pricing, convenience, and accuracy. Unfortunately, I cannot recommend the Aqua Doc product, if it is even still available,
