Pond Boss Forums INTRO Questions & Observations Pond murky

Yes, but you have to send the water out to be tested. The easiest way to do a quick "rough" test is to do a jar test.

Basically to do a jar test you take at least 2 clean clear glass jars. Fill both with pond water. Put one in the house near a window, put the other one in a completely dark room. Check them every 24 hours to see how much sediment is on the bottom of the jars. Make notes of how much and what color it is. Also note the color of the water in each jar. After 2-3 days report your observations here.
