Well it seems to be weather related now.

The warmer weather and sun returned yesterday and this morning so did the mass quantities of Gnats apparently. Must have swarmed the pool at dusk again as I did not go out there last night at all. This morning at the AM Reading the water was topped by a nice layer of Gnats once again. I have not done any night swimming at all partially due to this issue but is no lighting or anything other than moon light reflecting on the pool usually so looks like I can not do much more to prevent them from being attracted to the pool. Guess will just have to deal with it.

Hopefully it is not every night again this time. Is really time consuming to clean up and makes the pool very unappealing.
