API 5in1 Pond Water Test 25 Strips

Bon rapport qualité prix

These work well, easy to use and gives you a pretty accurate picture. Easy to read the colours and comes with a colour chart which was accurate.

These API POND 5 in 1 test strips make monitoring my pond’s water quality so simple and quick. They’re easy to use and give accurate readings for important factors like pH, nitrites, and alkalinity. I appreciate having all five tests in one strip — it saves time and helps me keep my fish healthy. The strips come with clear instructions and color charts, making it beginner-friendly. Highly recommend for any pond or fish tank owner who wants an easy way to keep water safe!

Test strips work well. Use 2 or 3 times a month to double check koi pond water health.

I thought the test worked very well, as long as you know that you have to keep the strip level and not let the water move from one area to another. My only problem is that I thought this also tested for phosphates. I waited 3 days for this test before I can add phosphate remover to my pond , and there is no phosphate test. Frustrated with that, although the other tests were great, and coincided with my other test kit, liquid.
