EasyCare 30064 PoolTec Algaecide, Clarifier and Chlorine Salt Cell Booster, 64 oz. Bottle

I used this product last year in my pool. Last year I switched to a salt water pool and the guy that installed the pool recommended this to help keep the pool free of algae and protect the free chlorine in the pool. He said to use two bottles when opening the pool and two when closing the pool and 16oz per week during the season. After reading the directions and the dosage needed for the size of your pool per how many gallons, I needed only 8oz. So every week I took a measuring cup and dumped a cup per week. I never had any issues with algae all season and this was the first time I had the pool open so I was a little overwhelmed about being a pool owner. When I closed the pool last year I did add two whole bottles of this to the pool just as advised by the pool guy. Most pools is this area of the midwest were really dirty and mine was no different.Update: 6-1-18After opening the pool this year I adding two full bottles of this per the pool guys advise. I added the necessary salt and have so far not had any issues. The pool is very clear with no signs of algae. I even have a neighbor that used my pool guy this year and they have own pools for 20+ years and have also had good luck and good things to say about this product keeping their pool clean and clear. I'm not sure if this product will work with regular chlorine pools but I'm sure someone can tell you. As for me I have had great luck with this keeping my pool clear and algae free.Update: 9-16-19After three years as a pool owner I have had good luck with this product. I have the same pool guy open and close my pool and two full bottles are used during the opening and closing. I have a little less that 15,000 gallon salt water pool and live in south MO. This year I have used this product less and forget to add it some weeks and just add two doses the next week. And still have a clean and clear pool. I noticed negative reviews and a question of integrity and validity of these reviews was brought up. I'm no pool expert, I've written several reviews on amazon and have felt fair in my honest opinion and I'm not paid my PoolTech or Amazon to say that. Now that said there's one thing I've noticed by being new to pool ownership, all pools are different. Where you live in the US, different climates, temps, rainfall, how hard your water is, how much sun does the pool get all effects how much chemical you use. If this product doesn't work in your pool it doesn't work, there's probably lots of factors as to why that is. I will say I have a great pool guy and his advise and knowledge is invaluable he has 30+ years of pool and spa experience and the only time I didn't use his advice was on the dosage because the guys at PoolTech probably also know what they are talking about. My brother is new pool ownership and he had so many issues with trying to clean us his pool. The pool store he was going to weren't selling him the wrong product to clear up his pool it was how he administered that product. Once he went to another store and that guy gave him advice from 20+ year knowledge his pool cleared up. So this is still a good product for me. Try it out if it works it works. If it doesn't ask a pro as to why your pool is still dirty.

This is a great product if used properly. Anyone who says it "doesn't work" or "don't waste your money" has no idea how to use it.This product makes your chlorine work better to prevent and kill algae. Proper water chemistry balance is always key. Once your water is balanced, add Pooltec to your pool, and it collects and holds onto the free chlorine in your water, helping the chlorine do its job. Use it all year round in small amounts to keep your pool clean and clear. I am not a pool professional, just a savvy homeowner who knows his pool.

This is a decent product--one of the best I've used in my 13 years of pool ownership. My pool guy recommended this instead of excessive shocking (since that can be hard on your liner over time). Returned from vacation to visible algae, uped the chlorine to 3 ppm and then tossed in the whole bottle (30,000 gal pool). In 24 hours, my pool was blue but cloudy with no additional chlorine. Added chlorine and brushed twice daily... By day 2, pool was swimmable, by day 4, pool was crystal clear as if algae had never happened and I never added more than 3 ppm of chlorine. Will now purchase to use as a maintenance product and will keep on hand in case of a bloom. For reference, I have a sand filter. Pricey product but worth it. Only major disadvantage is that it takes a week or more to arrive so purchase in advance of problems.

I’ve use this product for three years now. There may be a generic brand out there, but I haven’t been able to find one that works as well. Definitely reduces chlorine and definitely cleans up the water very quickly. Using a little goes a long way after pool is Opened. I would say my chlorine use is cut by at least a third if not by half weekly.

Easy to use, and does the job!

In 24hrs it went from a green pool back to a clear pool. Really wish I would of done before and after.

Worked great on our pool. Our pump wouldn’t work when pool was opened. We had to order a new one so we had about 1 week without it running. It kept our pool from turning black/green!

Added to the pool and can tell that it cleared algea.
