I do not use them myself because of this issue but if I had seen what I’ve seen now I would’ve rather gotten them. They are definitely cheaper than the maste test kit, and you can get an awful lot of tests too. And before everyone goes off and says they’re inaccurate, where have you done research? Or is this just some sort of indoctrinated belief in the community? I’ve seen a few people who run wildly successful businesses and fish rooms using test strips, and even at one point I watched them do a side by side of the two and get the exact same results. Hey did mention not all are accurate, but I’m kind of tired of seeing people pushed away from them and only one company (api) being recommended.
