Rapitest Pond Test Kit

This kit comes with 4 containers to put the pond water in and capsules of powder you pour in and shake, wait 5 minutes and check the color. Nitrite 0mg, Nitrate 2.5 those were very easy for me to read. The Acidity/Alkalinity test I couldnt tell if it was 6.5 or 6.0 because the colors look the same to me so I got in the pond up to my neck and removed all the leaves and dead plant waste I could find.

The Ammonia test is what really has me boggled. I cant tell if the color for ideal is a really light yellow or clear. With the ammonia test you have to put 2 different capsules of powder in and let sit for 30 minutes. The colors go from clear(ideal) to dark blue(fatal). Different colors of blue inbetween. My water turned a neon yellow. Anyone know what that means?

Do any of you use this? Is it reliable?

Thanks, Kathy
