Do I need to clean before I close? AGP, details in signature. I've fallen into some bad habits lately, and had a vacation, and let things go. The pool is a mess. It's not like HORRID stuff, but it's green and the water level is low from evaporation (I'd need to add water to run the pump)...

Hello — I shocked my pool last night around 8pm, added 56% cal hypo and some bleach, enough to bring the FC levels to 20 to 30ppm (getting rid of black algae). Brushed the pool good that evening twice. At 7am the next day (11 hours later), checked the FC levels twice taking samples from 2...

Hi, After owning the pool for several years, I thought I know it all but apparently I got things wrong. Long story short, we've been having out of control algae due to very high CYA (129) so we did as suggested by replace more than half of our pool water with fresh water and shock while doing...

Just bought a house that the owners didn't take care of the pool very well. It's 35k gallons with sand filter and SWG (not using yet due to swamp). CYA was below min reading of test, so been working on adding enough CYA to get to 40ppm and using a FC target of 20ppm. SLAMed for 2 days, using 24...

We have Pentair Whisperflo which is mainly used for the waterfall. We usually have it run 15 minutes weekly up until we had our freeze back in February. Since then, we have minor leak with the pump so we only run it for waterfall only when we need to, not weekly anymore. Today, I found algae...

Approximately 6 weeks ago I added CYA to my pool. I am not sure exactly how I did so, but I put to much CYA in the pool. Now the walls of the pool turn green about every 10 days, to the chagrin of my wife and grandchildren. I am sure the high CYA is hurting the effectiveness of the Chlorine...

There's been a bit of a heat wave in southern Ontario and my pool got away from me. Noticed some green sediment on the bottom. About to start a slam, but the dolphin has been sitting in there for a couple days. I see lots of threads about whether it's helpful to run the robot, but that not my...

I have a brown spot on pool sidewall that isn't going away. I have ph at 7.2, chlorine at 30 ppm 6 bags of shock, and cya is 50 ppm. Brushing 3 times a day, however spot grows yellow shell after 24 hours. I attach a picture of after I brush, and 24 hours of growth.

Hey everyone, I decided today to take my cover off and check out how my pool water is doing during the winter months...turns out it's not doing great. I have had this winterizing pill in there: Amazon.com : SeaKlear AquaPill AP71 WinterPill Swimming Pool Winterizer Pill : Swimming Pool...

Hello TFP, What an adventure. We had our pool re-plastered last year because the original plaster was starting to scrape our knees. The company we used plasters one day, leaves the pool dry overnight, and then acid washes the next day before filling it. Not sure I'm a fan of that, but it's...

Newbie here... TLDR:reddish brown stuff came out of return jet after filter had been off for 2-3 days...is it algae? With the rain, our pool filter hasn’t been running for maybe two days. I just turned it on and out of the return jet came reddish-brown...something. After a minute or so it was...

I noticed some of this on the floor of my above ground pool i thought it was dirt but when i wiped it up it had a slimy texture, it was more green in color so i assumed it was regular algae i scrubbed, shocked and did use algaecide (on Monday) yesterday the pool looked good aside from a thin...

Hi, I'm a new pool owner, pool was filled about 5 weeks ago. Up until last week I was manually adding dichlor and dry acid to keep the pool balanced, and didn't have any issues. Last week I added salt to 4000 ppm in preparation for the installation of a SWG, after adding the salt I had issues...

Hi! After weeks of trying to make my green pool clear and after having the chemicals balanced for two weeks I decided to use flocculent. I have an oval 18 by 33 above ground sand filter pool and I put the flocculent in last night. The flocculent as of tonight has still not dropped to the bottom...

My pool is bad. I’ve dumped a good $100+ in chemicals in last week and it’s still green. I’ve brushed and cleaned filters and everything I know to do. It only got this bad because it’s just me, and it was so cold and my pool sweep was down so I just let it go. Any tips..?
