Pool temp: 80
FC - Free Chlorine: 11.5ppm
CC - 1.0ppm
pH - 6.8
TA - 100
CH - 300
CYA - 23-24
All measured with TF-100 kit
Problem #1: Yellow/Brown build up on pool floor. I vacuumed pool bottom to waste last week and now its all built up again, all the while maintaining 10ppm CL. (attached pics) Do i need to shock again ... sigh (how high)?
Problem #2: Pool filter lets through visible particles. After I vacuum up some leaves/dirt and i'll see small pieces of debris coming out of returns and collecting under the returns on the pool floor. It makes filter setting kinda useless. I've attached filter bags to the returns for the present.
A bit of history on this one: I've changed out the sand (twice, changed pool sand brands each time). When I did this I inspected the laterals and didn't see any damage. The one part I don't quite understand is the junction between the filter valve-head the tube which goes down to feed the laterals. I can't tell how snug that connection is as there is no way to access this when i bolt the filter head on. Could a broken/ malfunctioning filter valve-head be causing these problems?
Currently use Chlorine pucks in a chlorinator after the filter.
Thanks for your help,
Chris
