Using Bleach to fight algae

Postby dstinyz » Sat 28 Jul, 2007 10:27

Please Help. I have easy set metal frame pool 15x48, 4440 Gallons.

FC- 1
Br-2
PH-8.2
TA- 320
CYA- between 45-50ppm
Total hardness - 520

I have read alot about using regular bleach to fight algae and I have found the BleachCalc. I just have a few questions reguarding this method.

Is it safe to use bleach in a vinyl easy set pool? What do I have to maintain my FC level at to fight the algae? (What is the differnce between FC and TC?)

Do I add the bleach while pump is running and do I have to keep it running the whole time until algae is gone?

Yes liquid chlorine is the best for liner pools. Pour it while you walk around the perimeter.

Yes keep your pump running 24/7 while you are fighting algae.

Also backwash or clean the filter twice a day while clearing up the pool.

The chlorine level should be off your scale for 24 hrs. The bleachcalc program should have told you how much to add. I would go with a gallon right at dush then repeat the next night. All living things will be dead. :twisted:

Algae

Postby dstinyz » Sat 28 Jul, 2007 17:40

Thanx a bunch! How do you back wash with a easyset pool? There is no setting to do this. I was also wondering when I purchased the pool kit it came with a CHEAP vaccum that you hook to a hose and all the stuff goes into a bag...this will not work to get out the algae because the particles are so small they go through the bag! Can I purchase another vaccum to hook up to this kind of pool? And if so how do you hook it up? Again thank you very much!

I heard that if you put cotton balls in the bag, it will help grab ahold of the dead algae...

Those little sweepers should be ILLEGAL! :evil:

Bleach is chlorine. Chlorine is bleach. Assuming your pool water is balanced, keep your pool at 3ppm chlorine at all times, and higher (10+ppm) to shock after rain or a large bather load...especially kids & babies. Use your test kit to check levels.

Using Bleach to fight algae

Wherever you pour your chlorine, do so VERY slowly. Personally, I think it's best to pour very slowly in front of a return in the water flow, but mixing up the water with a pool brush near the bottom of the pool will help as well (others say pouring into the skimmer works, but I think the water flow from the return jet at the deep end is best). Above-ground pools typically have very poor circulation near the bottom of the pool because they usually do not have floor drains. Bleach and chlorinating liquid is heavier then water so unless it dilutes in a vigorous water stream (return jet), it may sink to the bottom and can fade or degrade the vinyl liner.

Pre-diluting the chlorine in a bucket of pool water and still pouring slowly will help. This is similar to what needs to be done with Cal-Hypo as it does not dissolve quickly so adding it to the main body of pool water will often have it settle at the bottom and cause fading and degradation.

Using Bleach to fight algae

I've got an algae bloom right now and will be treating it this evening. The one thing I find frustrating on this site is there doesn't seem to be a general concensus on what chlorine levels should be, during the shock period, to kill an algae bloom. Some say 10ppm, while others say 15ppm.

Can anyone give some good hard science on what level to shock at to kill an algae bloom.


Thx
