NOTE: Below are my initial impressions of the Alkatronic. Since this post, my thoughts on this unit have changed 100%. Read the entire thread to get a better feel for the unit and its capabilities. @JonasRoman has been simply amazing in his support throughout this entire process for me (and others as well). I WOULD recommend this unit to anyone that is n the market for something to keep their Alkalinity in check. FWIW, I paid my own hard earned cash for my unit, I am sure you could tell that by my initial reactions. Once I receive my "quiet" fix (current batch already has the quiet pumps in place), I will do my very first full on review of the unit (never did one before with video and everything involved with it). Not an unboxing, lol (I hate those type of reviews - it absolutely means nothing to us in the hobby. We want to know how something works. I personally can read "what's included" from the manufacturer ) First I want to say that I was so excited about getting something that would allow me to measure ALK and I wouldn't have to do it anymore. I read up on the current units and thought that the best decision was to get the Alkatronic unit. Received my unit today and started setting everything up and was confused at first. Some things on me and others I can say that the instructions could have been better. Finally was able to get everything connected, calibrated, and ready for the first test. During the calibration I noticed that the pumps were very loud. I am not talking doser loud, I am talking extremely high pitch loud. So loud in fact that my Nest cam started sending me alerts about it heard a noise. I have a 5 and 6 year old and they do not trigger the noise alert as many times as this has in the short period of time that I have had it setup. Right before pulling the trigger to purchase the unit, something didn't feel quite right. Not a lot of real YouTube reviews, etc. so that should have been the first signal. The other was the manufacturer acknowledging the noise level of the pump and mentioning that there is an additional kit that is coming out that should decrease the noise level (which looks like it is at a cost). I even reached out the the manufacturer and requested a demo unit so I could give my honest feedback about how I felt about the unit. That obviously wasn't granted so I purchased it anyway. I was told that they have done all of the testing and that the unit was rock solid. Ok I accept that (not that I was trying to get something free anyway, just wanted to see if I could test). When you pay $1000 for a piece of equipment you expect it to be top notch (specially in this hobby). I do not have experience with the other units on the market so I do not have anything to compare this unit with. I will soon because it will be getting boxed and returned. Now to the issues that I feel are deal breakers for spending this kind of money on this unit: 1. You can do absolutely nothing from the web interface besides view the measurements and trigger another measurement, that's it (when you can get it to connect to it that is). Yeah the app is nice, but why doesn't it work with both bluetooth and Wifi at the same time? 2. The instructions made this way more complicated to install than they needed to be. KISS. You can get into details about this or that further down the manual. 3. Did I mention that this is SUPER loud. My nest cam is sending me alerts about it heard a noise and it is at least a good 30 feet away from the unit. Did I mention that it was loud. 4. There is absolutely NO way that I can use this to take measurements at night with the kids being about the same 30 feet away from the unit. 5. I installed the app of a different phone and the unit did not show in my login. I know it likely has to do with Bluetooth and all, but at least it could show that I do have a unit under my account and maybe for a pair or something. 6. At this price, there should at least be a double junction pH probe included. Here is a video that I made that somewhat demonstrates the noise-level. It is much louder in person than you hear in this video. I am posting this so you can make your own decision about the unit and not be swayed one way or another based on the warm and fuzzies in the original thread. If I could make this decision again with what I currently know, I would have waited for the Trident. Still going to give the KH Guardian the benefit of the doubt since it has been on the market for a bit. Hope to have a better experience with it.
