Ph Test Strips Ph Controller 1-14 Litmus Tester Paper Soilsting Kit Saliva Test Tools Strips Water Quality Testing

Does not change color at all strip. I kept it in the water for a minute, maybe more. I tried in an operating long aquarium and in an empty one-it's two weeks behind. The result is the same-two wet yellow strips.

It came in 2 weeks, but the seller did not want to send out, the order was two more weeks in wait, I myself extended the waiting time. Sent after trying to cancel the order.

I dont know how I lived without it before!!! Super!!! I will still order! I recommend it to everyone!!! Seller top!!!!

I don't even know if I can believe it, but I believe as long as everything is alive after the aquarium starts.

Everything is super, the product fully corresponds to the declared description, there are no complaints
