How long should it take to clear black algae

[joecus]

Thanks, I will continue to add the bleach. I am really at a loss. Is there anything other than an algae that could cause this?

High ammonia from something that was added to the pool or from the biodegradation of CYA over the winter, neither of which apply to your situation. I know it is frustrating, but keep adding bleach.

Today, is sunny and I'm back to adding tons of bleach. My test kit is the Taylor one recommended here. I do want to switch to a higher bleach content. Is there any online store you use to order 10 or 12%? Also, please explain how much of the 32oz would = 128oz of the 5.5. It sounds like two quarts = 1 gallon but not sure. As far as the inconvenience 0f gallons, it's not a big deal. It's actually funny the comments I get from the cashier when they see me buying all their bleach. I pay $1.47 per gallon. How does compare to your price?

Shipping costs would negate any savings over your current price, which is actually very good if it's 6%. A 5 gallon container of 12.5% weighs 40+ pounds. Is your bleach marked 5.5%? Even at 5.5%, a $1.47 a gallon is good. Are you sure it's a gallon? I don't see gallon jugs around here anymore. They're either 96 oz jugs or the 182 oz jugs.

Yes it is 1 gallon. It's a store brand (pathmark). It does not give the % on the label. I've tried to look up the % on the web without any luck. The directions match Clorox so I'm assuming it's 5.5. I've just ordered an ammonia test kit to see it that's my problem. Just a long shot chance. Last year I did have a major issue with one of the algaecide. The product name was United Chemicals Black Treat 3. It was a very weird problem, after adding this product, whenever I added chlorine, it would turn the water light green. By morning it was back to crystal clear. The water tested positive for metal. I bought a magnet/powder from my local pool store and mixed it with the earth. I did this along with few partial refills and the problem went a way. I'm thinking this may be some sort of residual from that problem. Any thoughts on partial doing partial refills. I have not been able to confirm the algae (smear test) due to me scrubbing it away on Saturday. I cannot see an algae present right now. One thing I have not been doing is running the filter 24/7. I reread the article Watermom put up and they suggested running 24.7 I am going to start doing this today.

I have a new development. I can't believe what going on. As I told you, my kit ran out of r0013. My last reading, two weeks ago, was 70. Last week I was using the strips and it dropped to normal on the strips 30-50. Today, I used the strip and it's showing zero. Now, I really need help. Please let me know what you think. Thanks very much.

Stick with the reading you got with the R0013 reagent with the black dot tube. Did you order more R0013 reagent?
