Applied Biochemists Swimtrine Plus

I have waited for a couple of months because I wanted a high degree of confidence in this product before I recommended it to others. I have tried many products to tackle both green and yellow algae in the past, all have failed. The reason they failed is because unlike Swimtrim, they all require a chlorine shock/boost in order to be effective. As soon as the chlorine is used up which can be 17mins in strong sunlight, the previous products lose their effectiveness and the algae returns. Swimtrim uses copper and requires no chlorine shock when added, so if the chlorine level drops, no problem, it continues to protect your pool. I might add that on first application you will need to use a whole 16oz bottle, after that it's just 3oz per 10,000 gallons every 2 weeks, so very economical. I just use a 5 gallon bucket, fill it with pool water, add the 3 ounces, and then pour slowly back into the pool round the whole edge of the pool.

Good

Great product. Really works.

Received my order in timely manner. This is the only brand of algaecide that I will use in my pool. It does a wonderful job keeping it algae free!

I have been using this product for 20 years and no other product works better. Pool opening and closing its all I use. And maintenance dose all season long.
