I've been lurking here for a couple of weeks now gathering information to try & correct an algae problem that's taken hold of our pool. I'm hoping to get it back in shape for a little bit of fun before the season ends.
Here are the details:
Haywood pump (not sure of the size) w/ 85 sq ft cartridge filter
Test kit Taylor K2005
Background: The algae problem started 2-3 weeks ago. We had been treating our pool once a week or so w/ cal-hypo and have a 3" tablet feeder which we were keeping 1-2 tablets loaded in most of the time. At the worst, the pool was very green & very cloudy. I started treating it by dumping in a lot of cal-hypo (48%) and then a lot sodium-hypo (10.8%) w/o success. I then found this site After reading here & buying a decent test kit, we started on the "Turning your Green Swamp Back into a Sparkling Oasis" plan last Thursday by first draining & refilling about 1/3 of pool because the CYA was ~90 Friday evening we began checking & dumping cal-sodium into pool every 1/2 - 1 hour to maintain pool at shock level for 5-6 hours. On Saturday, we checked the pool about 4x and brought it back up to shock level. By Sunday, it was blue / gray and cloudy. Sunday - Tuesday, we checked the pool 2x a day, morning and evening, brought it back up to shock level.
Here's the morning numbers after bringning the pool up to shock level (FC=13) last night:
FC 7.5-10 (I have a hard telling between the colors on the test kit.)
As you can see, we're still losing FC overnite and quite a bit during the day. (It had dropped to 1.7 by the time I got home from work yesterday.) The pool is still blue but very cloudy, though I can make out the bottom of the pool ladder.
Here are my questions:
1. Should we put the tablet feeder back in now to help hold the FC level during the day?
2. I vacuumed the pool on Sunday but we have not actually got in the pool to brush all the walls down real good. Is this recommended at this point?
3. What else should we be doing to get it sparkling clear?
Thank you for all your help so far and going forward
