That means that the water is way too basic. An extremely basic water level can be as dangerous as extremely acidic water. We have also spent time gathering Benthic Macro Invertebrates. These are the little creatures that swim around on the bottom of ponds. You can see these little bugs with the naked eye.
Invertebrates are indicators of water quality.
In our case, we found a wide variety. This is good because the greater the variety of creatures, the better the water. So far the information we've gathered does'nt provide any answers. We aren't going to be stopping our research once winter comes though. We plan to do what we can during the freeze, but once spring comes we'll be out looking for answers at the pond again.
