tingly water

[aylad]

The tingly skin was probably caused by the chloramines being formed when the chlorine combined with the impending algae. Don't kow about the bubbles...

Algea gives off oxygen, at least in ponds and fish tanks... figure it does in pools, too.

With a CYA of 70, your FC should be 5-10 and 20 to shock, according to the best guess table.

Grace is right. Algea is a plant and it pulls CO2 out of the water and produces O2 as a by product of photosynthesis. The little bubbles are the O2. Algea in the oceans is a major player in the regeneration of O2 in our atmosphere.
