Beat pool season ever,
Date:August 2, 2010
By kpool

Pros: No algae
Cons: None yet
"This is the best pool season in regards to maintenance in years. I was trying to decide on an algaecide this year and selected this based on the ingredients and something i had read on another pool care site.... we've had our pool for 16 years and started with chlorine, switched to baquacil for several years, back to chlorine...... out of the 16 years we probably had 2 trouble free years.... until this year.......i bought 24 pk of shock and this algaecide (i usually go through tons of shock and a few bottles of algaecide trying to keep the algae killed and "trying" to have clear water).... We have a 24' above ground and don't cover it over the winter... we continue to scoop fallen leaves out until the end of fall. In April we had a few nice days so i scooped out most of the remainder of the leaves and mixed 2 bags of shock in a bucket of water and dumped in the pool to get a jump start (before filter). Upon actually opening the pool the middle of May (connecting the filter) i added another bag of shock and filled our floating chlorine dispenser with four 3" chlorine tablets and added probably 6 ounces of the algaecide. I have not used any shock since.. I have used this algaecide faithfully every sunday and have not seen one bit of algae all year. Our pool water is so clean, clear and sparkling.... we usually fight cloudiness, algae etc. I replace the tablets when gone add the algaecide once a week and this has been the extent of my maintenance this year. I actually love our pool again. I will not open the pool again without this algaecide... I even bought two of the sparkle cubes this year as i used one last year and it seemed to help but still had a few algae blooms... i haven't even opened a sparkle cube yet...... i am very happy with this product."

Economical, but . . .,

Pros: Inexpensive
Cons: Not completely effective
"I purchased this in part because the recommended dosage makes it economical. Using the proper initial dose and maintenance doses, and an extra maintenance dose after a rain, I noticed green algae growth after about two weeks. Another initial dose, another maintenance dose, an an extra maintenance dose after more rain and I am seeing new algae (again after about two more weeks). I am going to increase the rate of maintenance doses and see what happens. Basically, I'm happy, but I think the recommended dosage is a little light. When applied, the algaecide is cloudy, but clears quickly. I use conventional chlorine based pool chemistry."

Pros: It works even under the worst conditions
Cons: haven't found any
"It has done almost nothing but rain all summer. We literally had rain 26 days in June and are on a similar trend for July which is usually a recipe for all kinds of Algae growth. I just checked the pool this morning and still no sign of Algae. I'm sold!"

Pros: Easy to add
Cons: None
"We were beginning to get some algae on the liner of our pool. I wanted to order a non-metallic algaecide since we had staining before from copper. I ordered Algaecide 50 put in the recommended amount around the perimeter of the pool and the next day it was all gone! Amazing product!"

Great stuff,

Pros: Works without residue
"Use this for opening and closing and never had a problem in 10 years. 2 times in 5 years I've neglected the pool and had a very green pool. Cleared up great with Alg 50, shock, Super Clarifier and Chlorine. Once in a pinch when I ran out I purchased Algecide from the local store and spent a year trying to clean off the goupy residue it left. Never again, I'm keeping it in stock!"

Algaecide 50 - Great Stuff,
Date:October 4, 2007
By JeffM
Pros: No Algae in my pool - does what it's supposed to!
Cons: None
"I have been using "In The Swim" chemicals (Including Algaecide 50) to open and close my pool for (4) years now. Never a problem. I have friends that have to empty better than half the water each spring just to clean and get their pool ready. I have never had to drain any water. "Closing" and more importantly "opening" has always been flawless. I will continue using Algaecide 50 as well as all the other "In The Swim" chemicals. GREAT STUFF!"

Wonderful Algaecide!,

By Cathy

from Beech Island, SC
Pros: Easy to use,cheaper than local pool supply
"18x36 in ground. Water murky, thick and visible green algae begining to show on steps:
Time to close pool so used one whole bottle and expected to have to vacuum out a mess. The next morning the pool was crystal clear and no dead grey algae to vaccum out so I didn't. I threw in 5 lbs of super shock and closed her up. I love this algaecide!!!Will order more for opening next pool season!Oh yeah was here two days after I put in the order and no shipping fee just a handling fee

By Current
Pros: Easy to use. Works very well.
Cons: none
"This algecide is better than any other product I have used in our pool. Having a 15 year old concrete pool sometimes algae becomes a problem due to the rough insides of the pool. Applying this algecide is easy, just pour it around the edge of pool. Sweep algae off edges of pool and it is gone with in a day or 2. Better priced product than same kind at pool stores."

Pros: Works- for along time. Its worth the price.
Cons: It cost a little more.
"When we switched from "store bought" to In the Swim- We don't get algae-period. People see our pool -especially in this latest heat wave we have had and always ask what we are using- its that easy. No black, green, white or any color algae. Our pool looks great."

Very Effective, Low Cost Product,
Date:August 10, 2007
By Todd
Pros: Very Effective, Low Cost
Cons: None to note
"This algecide product works as good or better than any other product I have tried. There are no issues using this product with vinyl-lined pools, such as the one that I have. It is also reasonably priced -- typically less than what you'd pay for a similar product at a brick and mortar store."
