Review on LiquaGen - Dual 6 Stage Under Sink RO/DI Water Filter System for Drinking & Aquarium (pH Alkaline, 100 GPD) by Stacy Watkins

I like that you get a great product at a reasonable price. I bought it primarily to add water to my 55 gallon tank. That's the yellow line I show in the video. It provides deionized water with a pH of 6.86 and a TDS of 20. Drinking water from the filter through the sink faucet has a TDS of 36, and my unfiltered water has a TDS of 0 f 365. So. it works really well. TDS are fully soluble solids. I've installed them before so this wasn't a first for me but I have to say the instructions in this kit weren't the best to understand and didn't explain the key elements of my particular 6 speed system. I also had to make several trips to the hardware store to pick up missing or incorrect hardware that was not included. An online dig video will help, but again, no installation video for this particular model would help. So a great product, but an experienced installer might be required if you are unfamiliar with DIY projects.
