Pool problems.

[localfinesse]

Thanks for all the help so far guys/gals. I posted a few pictures of my pool
http://slabindustries.com/brad/myalbum.html Does my pool look about 20,000 gallons? What is the best way to measure? Its 3ft at the shallow end and 6ft at the deep end.

I still have a lot of algae in the pool as you can see if the pictures. My water is pretty clear. My test results from Leslie’s pool are;

CL 5+
pH 7.4
Alk 120
CYA 120
Total Dissolved Solids 2500
Phosphates 500

That’s all they tested. They said I need to drain my pool to get the TDS down. I asked him to test my hardness but he said no because my TDS was so high. So what is the next step that I have to do? If I have to drain my pool do I need to drain it completely?

Also what do you guys use to clean the cartages? I have been using a hose and my thumb. Is there an easier way? Is the stuff at the pool store good to soak them in? If not what else can I use.

What do you guys recommend?

Thanks,
