Pretty basic tool no complaints works fine


This set is perfect for me and what I do. I really do not care to take extra time out of my schedule to go get distilled water and im working towards getting my own filter system. However in the mean time I use these and they work great, I use testing strips to make sure its balanced. If you anything like me, its made a big difference in my how my plants grow and the yields they produced since the water is balanced.
