envii Pond & Aquarium Test Strips, 5 in 1 Pond & Fish Tank Water Test Kit - Testing for pH, KH, GH, Nitrates and Nitrites for use in Garden Ponds, Fish Tanks, Aquariums - 25 Strips

Very easy to use and great to keep an eye on the pond water

Used for water quality test in wildlife pond. It gave me good readings, did have to look up what the chemical letters meant on the website but that's ok. They are fine for general water readings, not sure how useful they would be if you kept fish, that may require a more detailed testing kit. For me, the newts and dragonflies its fine,

Works well Simple to use. Great

These were very easy to use and the instructions are simple, although it does not say which way up to hold it (although this is obvious once you start). You simply wave the strip in the water for a few seconds and then hold in the air (without waving it around) for 1 minute, and then compare to the colour chart on the container. Mine said my pond was all 'OK' although it is super green and the various liquids I have tried don't work, so I think I need to try something else, but this product was useful for telling me that most levels are acceptable (pH, NO3 etc.).

o/k

I like the simplicity of the product, no fancy vials and Ph/Nh tablets or chemical required, just dip the touch paper into the water and wait for the colour change.

Does what it says on the tube. Pond checked easily Thank you Functionality: Easy to understand instructions and range of findings indicating health of pond.

Great product easy to use
