Never ending Algae!

Thanks Me,

I added another 4 lbs last evening as I said I would. Pool is blue and cloudy with dead algae this morning. Still algae on bottom. I'm going to vac to waste again and add more cal hypo. Well, spend and learn with the Yellow Treet. Are all the Yellow products the same and a waste of Money? Am I correct that the only thing you need to get rid of mustard algae is ballanced water and extended period of extra high cal hypo?

Thanks again!

Yes the best algicide/algistat (not sure about the spelling) out there remains chlorine. It kills just about anything. You'll need to maintain a high level of chlorine until all the algae is gone. Brush the sides, gently vacuum to waste. The pool will eventually turn milky with the dead algae in suspension but filtration and frequent backwashes will take care of that.

After that keep the chlorine level at around 5 ppm (with your 60 CYA) and you should be fine. A wee bit more than 1/3 cup of 65% cal hypo adds 1 ppm chlorine for your pool water. So say on a Monday you measure 3 ppm, you add 2 * 1/3 cup cal hypo. No more, no less.

Thanks for all the help. This morning the water is beautiful. Still a little cloudy but clearing up nicely.

This is great news, congratulations on getting the handle on the algae. Forgot to mention in my other post that using cal hypo will cloud up the water, _temporarily_, so don't worry about it. (If you do it in the evening no one will notice).

Again great work on the water, congratulations. Hope you still have some good warm weather ahead of you in your part of the planet, I took out the steps in my pool just last weekend, the end of the season is already over

Best regards,

No, I think the season is over. I'll close probably today or tomorrow. The water temp is down to 80 and no one wants to swim with it that cool. The weather out look is real good for nice cooler days but not for warming the pool water. I don't see any sence in keeping it open. What better time to close than with the water clean, clear and beautiful?

BTW my brother-in-law just told my wife that he has an algae problem in his pool. Looks like I will be passing on what I've learned here and help him out.

Thanks again! Talk to you next season.

Thank you, Me.
It worked for me as well (after struggling with cloudy water last summer and most of this summer).
I haven't seen this color water in years.
I, too, am grateful to you for your advice.

Does temperature make the cal hypo work better/worse?
I have been green for a couple weeks.
I am reluctant to close until it clears up.
Chlroine level is high.
gallons of algecide in the pool.
Sand is two years old.
Based on this string I will:
Add Cal hypo to my 10,000 gallon pool and run the filter for a day or two.
Do you agree?
