I turned off my salt cell and forgot to turn it back on for a few days (turned off Sunday or Monday, and remembered to turn it on today, Friday). There’s no visible algae. Do you think I need (a) bring up to range w liquid chlorine ASAP, (b) do a shock at SLAM level, or (c) do a full SLAM. I...

Jim, I found your response here. Great advice. I've run into too many algae issues over the past few years and I'm going to try something new. I'm just finishing up a SLAM and I'm trying your philosophy. When my chlorine level was appropriate, I was running my pump at 2850 for 2.5 hrs and 1800...

I noticed a tiny bit of algae on one pool wall the other day and knew I was going out of town this weekend, so I ignored it. Bad idea. This morning, it's still not tons, but it's on all 4 walls and a tiny bit on the bottom, so I shocked this morning and have the pump set to run all weekend while...

My Pentair Intellichlor IC40 salt cell from 2018 is not producing chlorine. It's reading low salt even though my pool has 3800 PPM and "ideal salt" is well below that (67 degree water). I emailed Pentair and they said that cells go bad after 2-3 years. Yay. I've read other threads about...

We had insane rain in SoCal and my pool turned into a lake briefly, but a quick SLAM made it crystal clear. My CYA is badly deficient and I need to get on that, but my balance is better than it's been in years and my CSI is -0.75. 1) do I need to worry about the CSI or just be patient and let...

I had another bout with algae, which was mind-boggling at 72 degree water temp, running the pump about 9 hours a day, and FC of 10 (my CYA is still a bit low -- takes so long to get it up with dry conditioner), but alas, it happened. I was out of town, so my SLAM this week has not been text...

Oof. First, unexplained algae. My chlorine levels have been fine. Pump running no prob. My pH was bad for a while but that shouldn’t cause algae growth, right? Second, and to the point, I’m in the middle of a SLAM, and just ran out of R-0871 for my TF-100 set. There’s no time to reorder from...

Just finished a lengthy SLAM for minor algae and cleaned by filter. I was way overdue for adding stablilizer. Local small business pool store guy said to take out the filter basket, dump in the whole 4 lb bucket of stabilizer into pump basket (without the plaster filter in the basket)...

My SWG was off for the winter. Last week, my FC level had dropped to 0.5 or 0. I noticed some color in the corners and hoped it was pollen, so I raised the FC to around 10 bc that was all the dichlor I had. finally did a filter clean today and color is back in corners. Think I need to SLAM, but...

I've having an issue with my salt cell reading low salt and not producing chlorine. Here are the specifics: IC-40 is one-year old The owner's manual says 3,600 is ideal (I've been reading the cell incorrectly and thought it said ideal was 3,000) The owner's manual says cell will read low...

My plastic clips that attach my solar cover to its reel keep popping off. Does anyone have any recs on reinforced ones that will hold onto the cover better and last longer? Thanks, Ryan

Something went wrong and we heated the entire pool to 100 degrees. The air temp is about 90, so it'll take some time to cool down. Do you recommend I shock the pool to get the chlorine level up quickly, or just adjust the SWG from 40% to 100% output and run the pump for a while? I don't need an...

I've done a poor job of maintaining my TA properly until recently (and my PH got high for a bit). Perhaps as a result, I'm seeing some serious scaling and salt cell waste (photos attached). 1) What's the best way to remove scaling? Something like Leslie's scale and stain remover (Leslie's...

Oh no. I just got back from a business trip and made the mistake of adding copper ethylenadimine complex to my plaster pool. What can I do to mitigate the damage? After I got home, I found my algae had not disappeared despite raising FC/TC to 5 and Ph to 7.5. I shocked the pool w 1.5 lbs of...
