Hello,
So I noticed my pool was not clear like it had typically been a few days ago, so I went ahead through the SLAM process. It is a concrete pool, and the CYA is a bit high at around 60 so I had to keep the FC levels around 26 ppm. After doing this for two days and brushing a few times a day, I only had 1 ppm loss from last night to this morning and my CC was only .5 ppm. I think I am in the clear for any algae, but the pool is still not as clear as it really should be. I do have a sand filter so I know it is slower going, and I was thinking about adding DE per the instructions on the site. What I am wondering is if there might be a problem with my sand filter? I know the common feeling here is that you do not ever need to replace sand, but I am not clear on what I should look for here in case I just might need to do so?
Would love some advice/ideas on this?
Thanks,
Chris
