thanks for all the information and advice
Dan I knew the tub was not sundance, not sure why i said that, guess I was reading another post on a sundance issue.
I have cleaned the filter, twice once before the clarifier and once after.
This week the water is much clearer. I have been putting in the chloine like a teaspoon a day. Haven't really used the tub this week, just once.
I will probably take the advice to empty it next week.
Really appreciate all the help.
