The Algae Wars Continue - - -

Thanks aylad,

I'm at work now so it'll be tomorrow before I can post those numbers.

My frustration comes from adding almost 6 gal of bleach and not getting a FC level near 20. I've got some dichlor (sp) from Wal-Mart but its got .63% copper so I haven't used it.

According to poolcalclator.com 6 gal of bleach should have given me a FC level of 19 on a 36,000 gal pool. How much is too much bleach to add at once? I would like to get this resolved so I can get it covered before it gets full of leaves.

Thanks for your help, I'm just getting frustrated with these results. I'm probably not hitting it hard enough to do the job . Early this summer the pool place tried to tell us we had some kind of chlorine eating algae. We've battled this problem all summer and.I'm willing to use this method I really need to see some results though.

Sorry, nothing like a rambling post to really confuse things.

LOL, all algae eats chlorine I suspect you're just not getting the chlorine levels high enough and not sustaining them. Post up your CYA level when you get a chance and we'll see.

At Last - - - (with respects to Etta James of course!)

FC 18.5!
CC .5
pH 7.8
TA 110
CH 120
CYA 20

To get FC to this level I added another 8.04 gals of bleach last night around mid-night. Finally something like I would expect!

And I have to go along with you aylad, I haven't had the FC levels high enough to really do the job.

Thoughts and/or ideas on my next plan of attack?

I'm really looking forward to getting the cover on it this year I'm sad to say.

Thanks -

And so it Goes - - -

Today at 1:00 p this was my results -

FC 13.5
CC 1
pH 7.4
TA 100
CH 110

Tonight after work (about mid-night) I'll add another 5+ gal of bleach. http://www.poolcalculator.com/ advises to add a box and 1/2 of borax to take the pH back to 7.8.

The pool looks a lot better! It's still cloudy but at least it's not green! There is still algae laying on the bottom I'm working to get out.

And so it goes -

Thanks -

Second Verse Same As the First (Almost) -

Today @ 10:40 a -

pH 7.4
FC 16
CC 0
TA 90
CH 120

Cloudiness is getting better! Tonight I'll add another 4.26 gal of bleach and 3 boxes of borax. That should keep the FC in the `shock range` and bring the pH back up to 7.8 or there abouts.

I'd appreciate it is someone would holler back if those are not the correct steps to take -

Thanks -

You're doing fine--now it's just a matter of maintaining that shock level over 12-15 ppm until you're no longer losing chlorine overnight. Keep the filter running as much as possible, preferably 24/7, to clear out the dead algae that's causing the cloudiness. Watch your pressure, and backwash the filter when it gets to 6-8 psi over "clean". If you don't notice your filter pressure rising, then you might try the DE trick that my co-mods use on their sand filters, where you put a cupful of DE in through the skimmer (just enough to raise your filter pressure by 1 psi) to help coat the sand and help it filter out smaller particles. You've got the right idea--now it's just going to take some persistence, some time, and some bleach

Thanks aylad,

Good to know I'm on the right track!

As I've discussed in another thread, I've been having trouble with my system not drawing as it should. I may have found part of the problem today. It's drawing some better for now.

I really appreciate your words of encouragement. From all I've read here I thought things were going as they should but its nice to have some conformation.

Thanks -
