Mosquitos

[Chad628]

This morning after two days of our first rain storm of the season I went to test my water in my pool and had the following results:

FC 5
CC 0
ph 7.6
TA 70
CH 380
CYA 50

On the surface of my perfectly balanced water was a layer of THOUSANDS of dead mosquitos floating around as well as a thick layer of them in the skimmer basket. Has anyone every had this happen? Why would mosquitos by the thousands be attracted to my pool water?

Haven't the foggiest notion why they would be attracted to your pool. Seems pretty strange to me. Has it ever happened before at any certain time of year? Really Odd.

This is just a guess, but you say your pool was re-plastered this year, if I am not mistaken fresh plaster gives off CO2 (I may be mistaken on this ChemGeek where are you?) CO2 attracts mosquitoes, it is how they locate dinner, follow the CO2 trail to their victims, so maybe they thought your pool was food.

p.s. had you recently added Calcium Carbonate to your pool? (same effect)

I did not add calcium chloride but yes my pool was re-plastured at the beginning of the year. This is the first time it has happened. The only unusual thing about yesterday was that we had our first rain storm of the season. I don't have any other standing or stagnant water on my property either.

I may have been mistaken. These winged insects in my pool might be gnats.

I found this post on another web site: http://www.poolforum.com/pf2/showthread ... nfestation

Gnats make better sense. I had them.

Yep, it sure would, we always get tons of em in the fall for some reason. Very annoying little buggers.
