Checked my CYA after having to pump out water on several occasions from thunderstorms. The CYA had been consistently in the 50-60 range for the last month or so, but had dropped to around 40. I run the pump from 11am to 5pm, with the SWCG set at 45% . My FC normally stays in the 4 to 6ppm range at those settings. I brought the CYA up to 80, and now my FC is reading 10ppm. Did increasing the CYA decrease the daytime FC consumption that much? I've dropped the SWCG down to 30% to see what happens.
