I Had the Worst Pool Algae This Spring
Dark Green Pool Algae With a Dreadful Smell
The pool algae was the worst on record for me this spring. Living in the northeastern US, we had an extremely warm winter and my pool froze for about a month: that's it. Pools in the northeast will generally freeze from November till March, this year, we were lucky if they froze in January.
I had black algae covering the bottom of my inground pool, and the walls were covered in green algae; there were worm tracks all over the bottom of the pool where they were eating the algae; it was a mess and it smelled like a swamp. My pool had never smelled like this... it literally smelled like the mud at the bottom of a swamp, but I really didn't think anything of it.
I started by following my normal routine: I dumped a 32oz bottle of algae control concentrate, and a few hours later super chlorinated the pool, and then vacuumed the algae with the pool filter on waste.
My Pool This Spring
I have been maintaining my personal pools for over 20 years, and for the past 7 years, I have maintained 2 pools each year. I open them, close them, and maintain them throughout the summer, and I have never experienced a pool this green, EVER!!! The pump was doing nothing for the green water, and the algae control never even turned the water a different color. Usually it would start killing the algae right away, but not this time.
So I went to a pool expert thinking that maybe other people were experiencing the same phenomenon as I was. He suggested I had metal in the water, so I should remove all the chlorine I just dumped in, and add a metal remover, so I bought his story and his chemicals, but I was very hesitant. I recommend sticking with your gut feelings as my pool was the same color and I was out $35 bucks. The algae were still winning.

Killing the Pool Algae Fast!
There is hope, there is always hope, and that's why I wrote this article. When I find a solution to a problem, I love to share my experience with others because I know I'm not the only one who has this particular problem. I couldn't be that lucky, lol.
I talked to another pool expert at a different store, one where the prices are a bit higher but the advice is priceless. He suggested I dump in 10 gallons of liquid chlorine into the pool, wait an hour, and then use an algae destroyer called Banish. Banish is manufactured by BioGuard, and it will destroy green, black, and mustard algae within 24 hours. At this point I'll try anything! So here goes another $76 bucks and a prayer; I just wanted to see a change in watercolor, anything to prove to me that the chemicals are working.
I dumped in the 10 gallons of liquid chlorine and waited about 2 hours, the water was still emerald green and full of algae. I thought, WTF, (Wednesday, Thursday, Friday) that's how many day's it's been, I started on Wednesday, lol. It was now dark out, and I turned the pool light on, I dumped in the 32 oz bottle of Banish, and the magic started to happen, the water was turning colors, NOT GREEN :) I let the filter run overnight and I never looked back.
My pool went from dark emerald green to blue in less than 12 hours. It was actually blue and semi-clear, and I could see the bottom on the shallow end but not so much on the deep end. It was blue and the algae was destroyed, yeah baby :) I can have my life back! It's very frustrating when you can't see any results. I didn't see any type of change in the green water in three days, and I was frustrated to the max.
I couldn't believe that all the chemicals I added to the water, didn't changed the water color at all. Usually you will see a slight change, but I didn't see any, nada, nothing! That's why I'm sharing my story with you: Banish by BioGaurd worked over night as you can see by the pictures. If I hadn't seen it with my own two eyes, I never would have believed it. I know the liquid chlorine helped in the process, but what changed the water color from green to blue was the Banish. I know because I watched it happen.

Questions & Answers
I have a 39,000 gal pool and have been battling the mustard algae that looks like sand on flat surfaces and slopes of the pool for two months. I have been vigilant every day. I am done with adding high levels of chlorine, brushing, and vacuuming to waste. I have been using 12.5% liquid chlorine. I also have cal-hypo 73% granules on hand. I bought two bottles of Banish. How much chlorine should I add and of which type?
I have the same problem, and I'm tired of adding chemicals that aren't doing anything. I have an above ground pool of the dimensions 18×33, how much Banish would I need or what would you suggest?
I recommend two bottles, use one complete bottle as directed, if you need a second dose, you'll have it, if you don't, you can save it for next spring. I guarantee it will make your pool water change color in seconds, not clear, but will change from green to cloudy blue. It will take a few days to clear, then vacuum the pool bottom as much as possible with the filter on waste so you don't filter the dead algae back into the pool. Let me know how you make out.
