United Chemicals Yellow Treat® 2 Pound Container

First off, beats Yellow Out not only in cost but also in effectiveness. Not only does it cost less, but you'll use a lot less. Oh and for the record, I wouldn't wish this situation on anyone except my ex.So my story began in the middle of May after the pool had been open for two months, gotta love the south. I visited my local pool store to tell them that my deep end was green (photo #1) and I couldn't see the bottom.....and so the nightmare begins. The associate told me that the water was balanced and all I needed to do was "Shock the heck out of it". That's $300 of awful advice. See picture #2 to see what the result is after shocking the heck out of yellow (mustard) algae.Return to pool store and got my guy. I showed him pictures and he let out a slow breath and said I had mustard algae and that it is resistant to chlorine so shocking it obviously did nothing. Obviously, thanks for that....another couple 100 dollars later and he issues Yellow Out with a set of directions. The nightmare continues. Treated it that night and the next day I see stuff on the bottom and it kind of changed color (picture #3) but still not quite there. I was told to continue brushing the entire pool to the main drain and if my arms and back weren't hurting I needed to brush again.Finally I was seeing progress after a WEEK of brushing (picture #4). The water was clearing and I was feeling good about my success. Not so fast!We of course had to leave town for beach vacay (I know first world problems) and while we were away I slowly watched my pool turn green on the Ring camera. Each day worse and worse. Now I'm crying. Turns out the pump quit on day two and my robot vacuum was just sitting in a mass of green spreading the blossoms through the top fan to the entire pool (Bring back photo #2).Order new pump, week delay, no pump=no circulation. That week sucked.Ordered more Yellow Out and repeated the process after installing the new pump. See photos 1-4 again. Got the water clear, broke my back scrubbing and of course the blooms came back in the SAME spot. Now I'm crying, sweating and about to give up. I've watched every YouTube video and read everything I could. What was I doing wrong???????So I noticed that Amazon "recommended for you" included Yellow Treat (mind blown even Amazon knew Yellow Out wasn't working) and it had a different chemical...what did I have to lose at this point. Oh and I highly recommend if something touched your water throw it away, if you can't throw it away, ie. robot vacuum, bleach the crap out of it. Bleach is different than chlorine FYI.Yellow Treat arrives, only needed three capfuls and super shock. Next day it looked like shock laying at the bottom of the pool (Photos #5&6), so instead of brushing I went straight hand vacuum to waste. That's right manually vacuuming the pool. UGH! Which means a lot of refilling the pool.Water is clear and more white stuff at the bottom next day. This was repeated through the week with less and less white showing only I wasn't going to come up short this time. Three more capfuls, a touch more shock, manually vacuum and boom, DONE!!! Water is blue and the robot is back in the pool doing its job(photo #7). Reminder, started in May and here we sit on July 25, finally achieving success. I will maintain it with No Mor Problems and continue my regular routine.This situation cost so much money. More than 2 grand if you include the new pump. I'm a Yellow Treat gal from this day forth, although hoping I'll never need it again.To all of you suffering from the same problem, good luck and stick with it. This freaking algae sucks!!!

I've used this product for 18 years and it works great here in the panhandle of Florida. I have always purchased it from my local pool company, but like many others, they significantly raised their prices due to the COVID19 EXCUSE. Of course COVID19 is long over and hmmm the phony COVID19 price hike remains in effect. It's not imported from the CCP or anywhere else so it's just another of many reason to, like taxes and government give aways. Once it is implemented it's like an uncureable dz.I always try to spend money at locally owned family business's in my area but there's no excuse for a 30% price hike due to alleged importation costs that no longer exists COVID19 is long over but some (even longterm reputable multigrnrational businesses enjoying decades of great reputation have, in some caseschanged their highly successful business model to match Wallstreet instead of mainstreet, a.k.a. their friends and neighbors.But again this is an excellent project.

I think it's the best around.Been using a couple years now while opening my pool. Fast shipping. No problems.

For the last few weeks “during rainy season” I’ve been experiencing yellow algae, while trying to keep my water quality correct. This seems to keep the algae in check even after monsoon rains, when water quality is impossible to keep at the right levels.Definitely would recommend this to someone who is experiencing the same conditions.

we had the hardest time getting rid of slime and cloudiness in the pool until we started using this product. We used many different algicides and nothing worked long term. My husband got in a conversation with a man who maintains pools for a living and he told my husband yellow alga is usually the main culprit, yet people do not treat yellow alga specifically, instead they (like us) try a broad spectrum algicide. I have been using this product as directed year round for a couple of years now and they pool remains clean and crystal clear, even after heavy rains or hot Alabama summers.
