TFP is a fantastic, cool website resource.
Here are pix of my pool.
Is that Black Algae on the waterfall rock? I see this a lot on pools with rock waterfalls.
My biggest problem, other than with paper wasps (that prefer my pool water instead of the traps I set!), is CH. It does not show well in the pix I took today but I have scale all around just above water line and the Jacuzzi overflow tile looks real bad when the pump is off. The standard answer in Phoenix metro is "it comes with the territory" but my tap CH tested this AM is only 120.
FC = 5 (shocked last week and my SWG is running 10 hours at 50%, I need to reduce either the hours or % a bit in order to get my FC down a little.)
CC = 0
pH = 7.7
T/A = 90
CH = 460 (using the 30 sec. method. Up from 450 from Shasta last month)
CYA = 30
Temp = 82
It is a daily task to keep pH down, I suspect due mostly to all the bubbling from the rock and Jacuzzi waterfalls and the aerator. I am thinking about turning off the water features to minimize pH increase but that's no fun.
As I said above, I shocked last week, up to 20 FC for 3 days, but last night when I swam over by the waterfall, I see about 2 inches of green algae under one of the rocks that does not get water except maybe splash from the pool. I suspect I will have to shock again after I get rid of it?
My major concern though, is the CH. I just cleaned my salt cell last month and it already has about 1/2 calcium buildup. I am thinking about draining my jacuzzi into the pool and then backwashing it down to the bottom of the skimmer. Unfortunately, I don't have the "rinse, waste" control valve on my sand filter just "backwash and Filter."
Anyone have experience with those magnetic wraps that are suppose to break down the minerals in your water when you wrap them around the plumbing? Are those affective at all or just "Snake Oil?"
You all rock!
