Help with getting pool clean

[tim665214]

I have been brushing my pool about 3 times a day, but I always brush it right BEFORE I add chlorine. So while the chlorine is not real low when I brush, it is a little bit lower than what I have been trying to keep it at.
My pump is a 1.5hp motor connected to a 200lb sand filter. But it is a two speed pump, so I run it on low when filtering and on high when backwashing. Each morning when I go out to check on my pool, the water flow coming back into the pool is very low, so I have been doing a backwash each day. That tells me that the sand filter must be picking up something, right? Also, I replaced the sand in my filter this year also.

Thanks for the help

I am beginning to wonder if I have a Chlorine Demand situation with how fast the chlorine is disappearing. The issue I have, is I am not sure how accurate my CYA test is, because my pool is so cloudy.

Have you done an overnight chlorine test to see how much you are losing?

[tim665214]

No. I have not got exact measurements late at night. I have just been testing in the morning and adding enough chlorine to get me back to 20.

I am thinking about taking my shock level to 30. Do you think that would hurt my vinyl liner, since I have no guarantee of my cya level?

I wouldn't go that high if it was my vinyl pool.

I have finally got it where the pool is a dull blue color. It is also still very cloudy. But when I sweep the bottom of the pool it does not stir anything up, and it does not change the color back to green. I guess this means I am getting close to killing all the algae. But why is my pool still cloudy? Also, I noticed tonight after dark when I would shine a bright light into the water, I could see what looked like little bugs swimming up to the surface. How do I get rid of them? I have been keeping my pool at a consistent 20 ppm of chlorine.

Thanks

It takes awhile for a filter to clear a pool and like I mentioned before your pump is awful big and may just be forcing debris, including dead algae, right through the sand instead of filtering it out. You might try adding a little DE to your filter. Sometimes that helps. Run your pump 24/7 while you are working to clear it.

As far as the bugs, I have no suggestions. Sorry.
