About 5 days into my first go-around with the BBB method.
Pool was a beautiful shade of emerald green . .
Test Results from Leslie's before adding anything for the season:
In an attempt to follow the BBB method, raised the pH to 7.2 (required 4 boxes of borax). Also added 4 lbs. of Baking Soda. Water began to clear even before adding any bleach! Thank you TFP! - Added 5 bottle of bleach the 1st night (121 oz. of 8.5%), with notable clarity the next day. Have added an additional 5 bottles since to maintain FC level. Alage seems to be dying nicely. So SLAMing is going well, I think.
Here's my problem. When I first started up the system, the pressure on my Eclipse Sand filter was 24. I have backwashed several times (that might have been a mistake), and my pressure keeps rising. Today is was 32, dropping only to 31 after backwashing. I read the forums a bit before this post and reailezed that I probably shouldn't backwash so much. Whoops. But I wondered what you experts out there think about the pressure. Is it normal for the pressure to be up due to the alage? Also - I seem to remember that my pressure was about 18 last year . . but then again I had a lot less water in the pool last year. Its full this year (was a wading pool last year due to repairs, and my unwillingness to pay the massive water bill to fill the pool with only a couple of weeks left in swim season). So does more water in the pool = higher pressure? I guess it would, right? So maybe 30 is normal for my filter? Hummmm. . . starting to go in circles here.
Well, any adivce is most welcome! Thanks TFP! I love being in control of my pool!
