Review: From green to blue in two days - Yellow Trine works great for fixing an algae problem. I cancelled my weekly pool cleaning service due to a new guy slacking on the job. Over the past couple months I've noticed my pool looking worse and worse by the week - walls started getting algae and eventually my water started turning light green. I complained, but the service guy either doesn't know what he's doing or just doesn't care, so I fired him. I decided to take it into my own hands before the problem got out of hand. I read Yellow Trine is perfect for preventing and battling algae, so I ordered from desertcart. It works as advertised on my 25,000 gallon pool. First I brushed the walls and floor to loosen as much algae as possible. I threw in a capful of Yellow Trine followed by a gallon of liquid chlorine in each end of the pool and left my pump on for 24 hours. The next day the remaining algae was gone from the walls and half the pool was already back to looking blue. My pump had full pressure and filter was white before the treatment... after the treatment my pump lost almost all pressure due to my filter collecting lots of green gunk. I cleaned the filter to restore pressure, vacuumed out the dead algae (did this twice due to lots of dead algae on the pool floor) and the next day the whole pool was blue again. Just need to clear the cloudiness and restore PH levels and I'll be set. Keep in mind I knew nothing about pools a month ago. If I can turn my pool from green to blue in a couple days, anyone can with this product. Highly recommended. Review: Works Great on Mustard Algae - Only chemical to obliterate the Mustard Algae! Use as directed then vacuum to waste. Do not let the debris flow through your filter. It will just end up back in the pool. After my pool is clear, a weekly application keeps the algae at bay. ## Features - BENEFITS: Quickly rids pools of mustard algae outbreaks - USE: Swimming may be resumed several hours after treatment - COMPATIBILITY: Works with all types of pools and all sanitizers including bromine, chlorine, salt water, ozone and minerals - FEATURES: Destroy deposits without leaving a residue - INCLUDES: One 3-lb container of Yellowtrine from Applied Biochemists ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00PM8Q96O | | Best Sellers Rank | #18,403 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #25 in Swimming Pool Algaecides | | Brand Name | APPLIED BIOCHEMISTS | | Customer Reviews | 4.3 4.3 out of 5 stars (428) | | Global Trade Identification Number | 00785336186238 | | Included Components | Pool Accessories^swimming-pool-and-spa-supplies | | Item Form | Granular | | Item Type Name | Swimming Pool Algaecide Cleanser | | Item Weight | 3 Pounds | | Manufacturer | Innovative Water Care | | Product Benefits | Controls Algae | | UPC | 788275312577 785336186238 | | Unit Count | 48.0 Ounce | ## Product Details - **Brand:** APPLIED BIOCHEMISTS - **Item Form:** Granular - **Item Weight:** 3 Pounds - **Product Benefits:** Controls Algae - **UPC:** 788275312577 785336186238 ## Images ![Pool 408622A Yellowtrine Swimming Pool Algaecide Cleanser, 3 lbs - Image 1](https://m.media-amazon.com/images/I/61VHRdh6pXL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ From green to blue in two days *by L***F on April 27, 2014* Yellow Trine works great for fixing an algae problem.
