I started with a yellow/green algae problem and bought this product. Followed the instructions on initial treatment and follow up, and the algae was killed. Vacuumed up the dead algae on the bottom and have had a nice clean pool all summer. Will continue to use this product.

Had some algae starting to grow in my pool. A friend told me to use super algaecide plus. I followed the instructions and noticed a difference in 2 days, by weeks end it was all gone. That was 4 years ago, and still no algae. I use this product faithfully every year. No algae ever. Even on the hottest stretches of summer. No algae.

I have been using this product for a couple of months now and my pool is alegea free. My pool is 17,500 gallons and I add 2 ounces a week after the original 4 ounces to start. I had been using Clorox or HTH pool products in the past and they did not work at all. I could add the algecide one day and the pool would turn green the next day. Nothing seemed to work until I ordered your product. I am so happy I finally found your products and will never use anything else !

25,000 gallon inground salt pool... 4 to 6 ounces of this algaecide along with 3 caps Pool Perfect + Phosfree once a week. Run my pump 4 to 6 hours daily. Backwash weekly. Burn out every other week. Check my levels couple times a week. Add water as needed. All done in a couple hours each week. Never a problem. Dohenny's... Great company, products, pricing, Highly recommend.

The product was offered at a reasonable price, so I decided to try it. Followed the instructions and within a few days I noticed substantial difference in the water clarity and that the algae growth was greatly reduced. By the end of the week, the algae was gone, and all that I have added is the maintenance amount for my pool size (4 .oz) I would HIGHLY recommend Doheny's Algaeside Plus product. I will definitely buy more when this bottle runs out. Thank you to Doheny's for offering such a great product!!

I bought this to clear algae blooms from my pool. This is a concentrate that you mix with water before adding to the pool. Quick acting and effective. Initial dose kills algae quickly, and may be used at reduced concentration to maintain algae protection once the initial algae problem is remedied.

This algaecide works like magic…I recommend skimming the bottom and brushing the sides and cleaning the filter for optimal results…putting in a little more algaecide works favorably and the ending results are amazing…absolutely amazing…. Always remember if it's super hot outside and you're tired then just use an additional bottle and let the water run 24 hr. Again you'll be amazed and get the pool on its way to sparkling water…..everything is about consistency cleaning the pool of debris….in the end the elbow grease you put into your pool will always comeback in clean sparkling water….ALGAECIDE WILL BLOW YOUR MIND AND THE WATER WILL BECOME SPARKLING….ONE OF THE GREATEST PRODUCT'S I've EVER USED….

After spending almost $200 on products at my local pool chain store around the corner my pool was still a green mess. I ordered Super Algaecide Plus at 3 pm and it was on my doorstep by 10 am the next morning. Used the product as recommended and 2 days later I was back to blue. Photos tell the truth. Doheny has won a customer for life. Thank you for great products and great service.

I followed the algicide directions as printed and the first treatment reduced the mustard algae growth but did not eliminate it. As per the instructions I retreated my pool and after 3 days my pool was cleared of the algae. I swept the pool sides and now my pool is clean. Great product that I'd purchase again!

I have placed several orders and each one has been canceled or never been delivered. I have called customer service several times and I am put on hold and waited no comes back to answer my question. Then the order is cancelled. I guess they don't want to sell to me. To bad I am in need of many products I guess I have to go somewhere else.
