Doheny's Total Algaecide - 4 x 1 Qt.

An easy to use and effective way to take care of algae. Not a miracle chemical, brushing and correct chemical balance still needed for this algaecide to work properly. Would definitely order it again.

I used this all summer and it kept my pool looking great

I have a 30,000 gal pool and for the past 20 years I couldn't get rid of mustard algea, I used yellow out and followed the directions, it got rid of it for about a week, I've tried everything super shocking and it came back within a week, I finnaly Bought Doheny'y total algesiide about a month ago and have not seen a trace of algea

I had an algae problem. I went to one of the big box hardware stores for chemicals. After 4 treatments with their "best" algaecide and making sure chemicals were balanced, my pool was still green. After one treatment of Doheny's total algaecide, my pool turned crystal clear. I wasted a lot of money not going to Doheny's in the first place. I won't make that mistake again.

Our old gunnite pool has pitted plaster. We could not stay ahead of the algae no matter how much chlorine and brushings. In desperation I tried Doheny's Total Algaecide. The pool is big - about 30,000 gal, and the problem was severe and recurring, so I bought four quarts and dumped two quarts into the pool. I kept the pump going for 24 hours. In ONE day the algae was gone and in TWO days the pool was crystal clear. I haven't had to add any more in over a month! This stuff works... kills algae dead!

Love this product. On the very day I heard an advertisement for this product I received the Doheny catalog, first time. What a coincidence! Decided to see if Doheny offered and there it was. Told my wife to order right away. Had issue with the first shipment that was returned due to damaged product. When I contacted customer service to advised that the shipment was returned before arriving at my home a replacement was sent out immediately and received within days. Great customer service and this product did wonders for our pool.

This stuff is amazing! It arrived So quickly after ordering. We've battled mustard algae and greenish water for the last 2 summers. This stuff cleared up the algae completely within 48 hours. Our water is now crystal clear and the mustard algae has not reappeared. We will definitely start every summer with this Total Algaecide from Dohenys.

Works better than the algaecide I purchased from the pool stores

After putting in an entire bottle, the algae only got WORSE! So I added another bottle a few days later with the same result.The recommended dose is less than half a bottle.The good news is I still have 10 more bottles. So maybe putting all of them in together will make a difference. Either that or the contents of the bottle is just colored water.

I would rate it O if I could. My pool water had just turned green. My PH was at 7.2 . Filter cartridges were just cleaned. My pool is 20,000 gal. I spread in 64 ounces of Total Algaecide. Its almost a week later and I now have Sparkling Green Water. I can't even see 4 ft deep in the water. IT DIDINT WORK AT ALL !!!!!!!
