Review on 🌡️ Seachem pH Alert Test Kit for Freshwater by Sander Savala

I've been using this product for six weeks and it doesn't work. No gradual rise in pH was seen that almost killed any of my discus. It initially worked but then became inactive with a permanent brown-yellow color. I pulled it out and tried soaking it in a 1:1 mixture of vinegar and water and then tested it in my tap water, which has a pH of around 7.6 with no change.
