Help!!! Can't get rid of cloudiness!!

[dang_pool]

Here is the test info: pool is an above-ground 17,500 gallon

Saturation index - .14
Total dissolved solids - 1,000
free chlorine -0.0
total chlorine - 0.0
pH- 7.6
CYA - 30
alkalinity 150
calcium hardness - 180
temperature - extremely cold!!

All season, the pool has been a cloudy bluish-green color. Last week they said my phosphates were high (1,000), so gave me phosphate remover and clarifier, which I added. No difference and that has been 4 days ago. My filter (D.E.) needs cleaned several times a day and has green matter on it when I clean it. Until the phosphate issue last week, pool place has been telling me all season that everything tests perfectly. When the above reading was taken last week, I had put quite a bit of chlorine in it the day before, and, as you can see, there was none left the next day.

Any help would be greatly appreciated, as I have poured a lot of $$ into trying to figure out the problem (including a new $300 filter, which I now know was not the problem.)

Are you replenishing the DE everything you clean or back wash it?

[dang_pool]

What has been happening is the water flow back into the pool goes down very quickly, even if the pressure has only slightly increased. If I open the lid and clear the d.e. and dirt off of the air valve, water flow increases for a while. Eventually, that stops helping much and I go ahead and start over - cleaning the filter and reapplying fresh d.e. I have never kept the filter running long enough for the pressure to increase 10 lbs, because by the time it increases by 5 lbs, there is hardly any water going through the pump and being returned to the pool.

I have changed the d.e at least 10 times in the last 2 weeks.

Something is very wrong, then, with your filter.

What size is your filter and how much DE are you using to reload it?

[dang_pool]

It's a brand new filter and the same as I used last year and the year before with no problems at all. Not sure of the exact size, but I put in 5-6 lbs. of d.e., as it instructs on the lid of the filter housing. What could be wrong with it? Everything appears to be working ok, as far as the d.e sticking to the filter etc.

CHANGE YOUR SAND,,,this happend to me I spent hudreds of $$,,,in chems,,,then I changed my sand and had sparkling water overnight!

Erin, Sorry, I've been having sciatica problems and haven't been able to spend as much time on the forums. Can't bear to sit, very long.

Sounds like you may have a 60 DE. When you first charge a DE filter you need to use about 10 lbs of DE, then with regular backwashing you should use around 5 lbs.

If that doesn't work, then I would have a pool repair company look at your filter. You shouldn't have to do what you are doing with a DE filter. You may have some hairline crack or damage that is causing your problem.

Bob - Erin has a DE filter, not a sand filter.

DE and SAND are two very different things...he has no sand in his filter.
