Hi All,
I live in Raleigh, NC and this is my 2nd year maintaining my in-ground 25k gallon sand filtered pool.
Was able to get it looking very good last year after a month of struggles and it was in great shape when I opened it this spring.
However, I made the mistake of using an algaecide (yellow out) prior to leaving for three days while away on business. Turns out this product, while it can be effective eats away chlorine and so when I returned the pool was a solid green.
I thought others might be able to learn from my mistake and be able to see what works and what doesn't in terms of bringing it back to clear.
I use a TF-100 kit to test and will be posting numbers and pictures daily so you can track progress.
Here is where my numbers were as of this Sunday, May 10th:
TC: 5+
PH: <6.8 (wonder if the Yellow Out lowered it or if the rain we had Saturday and Sunday dropped it?)
CYA: 35
TA: 20
FC: 7.5
Visibility:
Shallow End Floor: 0%
Middle Pool Floor: 0%
Deep End Floor: 0%
Actions:
-Skim
-Brush
-Vacuum
-Backwash (prior to adding chemicals)
Additions:
+40oz of PH Up (Pooltime Brand)
+5lb Cal Hypo Shock (HTH Brand)
