Yes, they work. I bought
"Yes, they work. I bought these along with the Pond Equaliser after all my snails in my wildlife pond died, well, more accurately, died along with any evidence they were even there in the first place. The water (rain) was too soft which the Pond Test Strips confirmed. Pond Equaliser corrected the problem & I can now test the water to make sure it doesn't happen again. New inhabitants are now thriving. Will buy both products again."
