Read the article on how to shock and you need a good kit to ensure you're really at shock level for your CYA.
Do you know what your CYA is?

You have passed the OCLT when: 1)You lose 1ppm or less FC overnight, & 2)You have .5ppm CC's or less, & 3)your water is clear.

It would be helpful if you could post a full set of test results to include:
FC
CC
pH
TA
CYA
CH

If your water has you worried, do an Overnight Chlorine Loss Test (OCLT), and if you fail, then follow the Shocking Process until:
1. CC is less than 0.5 ppm, 2. An OCLT shows a loss of 1.0 ppm or less and, 3. The water is crystal clear.

And answer all your questions about your pool. If we can answer them from afar with only test results... imagine what you can do right there by your own pool!

You can take a water sample to a pool store and have it tested. Post the results back in this thread.
Pool store testing is hit/miss, but we should be able to get enough info to at least get you started.

Having a good test kit will put you in control of your water. The fav around here is the TF100. Link in my sig.

What size/pounds is the sand filter?

Hey knightrider, make sure you read/reread http://www.troublefreepool.com/pool-school/shocking_your_pool its a process and can take some time. For your CYA of 40 ppm, poolcalculator.com is giving a suggested minimum shock level of 15 ppm, so to do the shocking process correctly, get your FC above that and keep it there until you pass the three criteria in the shocking process (also in my sig). You can use poolcalculator to calculate how much bleach/liquid chlorine to add.

Thank you! I did miss it...Although it was 25, which is why it does seem to be clearing albeit slower than I'd like...
