Hi, 1st my results
CYA 85 -90
I've been keeping the pool chemicals up to the rate as per Pool Calc. , but we've had some rain and I did fill from the tap before the rain. I know they are a little high now but I can't seem to get the pool sparkly. It is dull and still not really clear. It's not bad but its not totally clear either.
I've got the SWG on 8 hrs. a day @ 100%. I had a hard time keeping the chlorine at 5 as per suggested levels. I tseted and put on more stabiliser but I still find it hard to read the black dot test and may have overdone it.
Was wondering about changing the sand in the filter but lots of people say you don't have to. I would say it hasn't been changed in 12 years. I did flush it 1 month ago by taking the top off and filling and overflowing it.
Any suggestions much appreciated.
