Review on 🔧 Enhanced Performance: SimPure Replacement RO-Compatible Filtration System by Doug Hook

Excellent work! I use RO/DI water for my aquariums. I had to replace my old filters but hate how expensive they are. I decided to try these products and I am very satisfied with the result. While my original filters had a 1 micron filter, these have a 5 micron filter and I wasn't sure how much that would actually do. After filling a 5 gallon bucket (to rinse the filters before full use), I tested the water. This was at 0.03 TDS. Original filters when new and good show 0 TDS. So I didn't think it was that bad and that's the way it should be. I can only watch my tanks and see if anything changes. I filled my regular water reservoir with these new filters and then did another test. He read .01! It's fantastic for the price! I will continue to buy these.
