Since last season, I've had debris issue on the Autopilot SWG filter. At the season end, I found a crack on top of manifold when I opened it. I purchased a new one (from Amazon Pentair e-store) and replaced it, hoping this season the problem could be resolved. Unfortunately, the debris issue is...

I want to bring up the CH level. Can I use calcium chloride from the big box store? A lot of them are for Ice melting. Can I use them? or which brand of product I better use? thank you.

I have an impression that CH is not important at all for Vinyl Liner. I just don't know if this is a valid statement. My pool has very low CH, and the local pool shop warned me to bring up the CH. I just want to make sure which is correct. thank you.

I don't use Clorine, but Salt Chlorine generator. Is it gonna do the same thing, or pour some extra liquid chlorine to help clean it. thank you.

I do have some sunscreen issue after kids played. I checked online. people suggest use some Enzyme product to dissolve the organic product. Do you think this is useful? Sounds like it can help clean the scum on the perimeter of the pool as well. Is that true? if so, any suggested product or...

After kids playing water with UV sunblock cream on, part of the water becomes white, and some white stuff floating on the surface as well. Is this normal? what should I do to get rid of it? should we avoid using sunblock cream when playing in the pool? thank you.

There is no metal in there. I went to the local pool store to test the water once (just to double check my test result and confirm). and there is no metal in there. The water is one year new. (I changed the all liner last year. ) since then, never used any copper based products. Setauket is...

The kit I use is Taylor K-2006. I trust this kit, since I've been using this for several years. Actually you remind me something. the night before last, I changed from "filter" to "recirculation", since otherwise the flow will be blocked overnight. (I had this experience the 1st night of...

This is the 4th day of SLAM. From yesterday night to today, no change in water color. still green. CYA is almost 30. FC barely changed 12.5 to 12. CC is unchanged 0.5. Plus there are some milky stuff on the surface of the water, please see the picture I attached. Can you please let me...

This is the 2nd day of SLAM. CYA < 30ppm (I think it is about 20ppm). FC dropped from 12ppm yesterday night to 8ppm early in the morning. Kept pump running in medium speed overnight on "recirculation". Water color is still light green with a little bit foam on the surface. What I am gonna...

I opened the pool for 1 1/2 days, and have been SLAMing it. The water turns from dark green to light green now, with some foam on the surface. Now my question is that I do have to do backwash almost every 3 hours (keeping the pump run at highest RPM.) In other words, every 3 hours, the PSI...

Thank you guys for your quick response. Within this 1 1/2 days I used 6 bags of 1lb pool shock ( I know my CYA is low, so I want to add some in the meantime.) and 10g of liquid chlorine. Yes. It is pretty much like the link picture shows. I actually did vacuum bottom as well to get rid of...

I opened the pool yesterday morning and have been doing SLAM for almost 1 1/2 days. However there are a lot of disgusting foam on the pool surface. btw, the water color is still a little bit light green. Can you please let me know why there are foam and how to get rid of them? (seems like the...
