Following "Super-simple" guide but have algae

[tgthomson]

Hi,

I've been following the "Super-simple" guide all summer for our pool (7000 gallon intex pool with a sand filter) and it's been working great, but we just got some algae a day or two ago. I vacuumed the pool, cleaned out the filter, and added an extra dose of clorox yesterday morning and shocked it with four doses last night. Today the pool water is cloudy and tinted a little green.

My CYA is ~40, and I keep the chlorine level at ~5 and pH at ~7.5. (I didn't get a chance to take a chlorine reading this morning, tho).

Do I need to shock it again? Add more clorox?

Thanks for your help!

Since you've got a K2006, go ahead and use bleach to take the chlorine to 10 - 15 ppm. A single gallon of 8.25% bleach should get you there.

Thanks! I brought the chlorine up to ~12ppm this morning and this evening the pH is up around 8.0 (from 7.5). Is that normal?

I think the pool was looking better, but it's night now and I can't tell. Chlorine is down to around 8ppm--I'll bring it back up to 12-15 for the overnight.

Yes, the pH rises when you add chlorine bleach or chlorinating liquid, but it will drop back down when the chlorine gets used/consumed. Maintain the higher chlorine level until the pool clears.
