FLOC ISN'T WORKING

Postby Bunny123 » Mon 25 Jun, 2007 05:24

Okay I am at my wits end. I have been working with my pool stores to try and get the algae out of my water. I added conditioner/stabilizer. I shocked my pool 5 times. Got my chlorine up. All of my other readings were looking good. I vaccumed and brushed brushed brushed! I added alaecide. Added phosfloc yesterday at noon. Now it is 5:30am and the top of my pool is still a slimmy green. Nothing has settled that I can see. I followed the directions for the floc to a T. What is going on? Why didn't anything settle to the bottom yet? I need some help BAD.
Thank you.

I suspect that your Free Chlorine (FC) levels are not high enough at your Cyanuric Acid (CYA) level to kill the algae much faster than it is reproducing. Can you post a full set of water chemistry numbers -- especially FC and CYA levels (pH would be good as well)? Calcium Hardness (CH) and Total Alkalinity (TA) are not relevant for getting rid of algae, but they would be good to know to understand your pool -- cloudiness can occur if these are out of balance, independent of algae.

I had a similar problem and learned that I had a very high level of phosphates in the water. Those high levels come from nearby trees. High levels of phosphates allow algae to grow even in well balanced water. A pool store can check your phosphate levels. The cure is a specific chemical that you add to the skimmer basket as the pump runs. The chemical then creates a layer in the filter that collects the phosphates. You run the filter for 48 hours straight and then backwash the phoshates out. Hope this helps.

Floc doesn't kill algae. It just coagulates the tiny particles in the water so they can settle out or be filtered. It's the last step after everything else is fixed. That being said, Floc takes 24-48 hours to settle out with the pump OFF. Until it settles it looks as if nothing is happening, then it seems to settle out all at once. If it hasn't been 24 hours, keep the pump off and wait (assuming the algae is actually dead of course!).

floc/algae

I'm having a very similar problem. Pool was extremely green. I kept the chlorine levels high for days and it seemed to clear it up. I've taken samples to store, they tell me everything is perfect. Pool is SOOOOOOOOOO very cloudy. Beginning of last week I went in to get floc, they sold me some enzyme thing that's supposed to eat all the particles and you don't have to backwash. I did two applications, two days apart, using the whole bottle as was suggested. Friday I shocked again, as pool was starting to get a green tint again. Saturday I used a liquid floc (which i've only ever used the granuals.) Tonight, pool is still cloudy, didn't settle in the least little bit. I've also noticed that my chlorine levels just won't seem to stay in the normal range. I'm guessing this is because maybe there's still live algae that I can't see???? Please help! I really want to see the bottom of my pool :D

It's a little hard to help when you don't give us more information like your pool volume, test readings (a full set), what type of pool, what type of filter.

You've thrown a lot of "stuff" in your pool. Floc & clarifier are something that I only recommend as a last resort. Trying to use something that blasts the particles so small so you don't have to backwash is sort of contrary to what you use Floc & clarifier for. I just can't imagine what that product must be.

So get us the information we need and we can better tell you what you need to do.

Pool Volume in gallons
Pool Type as in vinyl, plaster, fiberglass
Filter type as in Sand, DE, Cartridge
Total Chlorine
Free Chlorine
pH
Total Alkalinity
Calcium Hardness
CYA - stabilizer

my pool is an above ground 18ft across round 4 ft deep. approx 7,500 gallons. Vinyl lining. Sand filter. Changed sand about a week ago.
Last weekend I had the store test my water. These are some of the readings:
Free Chlorine 0.3 (Low)
Total Chlorine 1.6 (ok)
ph 7.8 (high)
Cyanuric Acid 10 (Low)
Copper 0 (ok)

They had me add a conditioner - stabilizer (full bottle)
I shocked it 5 times and got the chlorine level up to a good reading (tested with a test strip)
I vaccumed and brushed a few times.
I added algaecide and then added the phosfloc. This afternoon it will be 48 hours. I can see down about 12-20 inches but still looks pretty bad.
What should I do??? I have been spending a fortune and have yet used it in 2 months.

You should do this following in order:

* - Recheck your CYA level. With a level of 10, no matter how much chlorine you add it will all disappear in a few hours thanks to the sun. You want a level of 30-50. It's sunscreen for your chlorine.

* - Shock your pool to a chlorine level of 10. Keep it there for at least 24 hours.

* - Run your pump and filter 24-7

* - Keep brushing to make sure everything is killed by the above.

* - Wait. Only after you have done the above will your filter start to clear the water and this could take a week.

Chlorine is your friend, but it has to be present 24/7.

Good luck!

I came home from work and it looked as though alot had settled. I vacuumed up as much as I could. I noticed alot of algae on the sides so after I vacuumed I brushed the sides and added more water to my pool. Will everything that I brushed off of the sides settle again so I can vacuum it up? I still do not have my filter on allowing everything to settle again? When is it safe to shock? Obviously I do not have my filter running in order to let the floc work so I figured adding more shock at this point will not circulate.

Thanks for your help!

I am still working on getting my pool clear. I got rid of most of the algae I believe. All of my levels are good now. I continue to keep the chlorine levels up. Scrub and vacuum daily. Water is still very cloudy. I can not see the bottom. I keep using a clarifier as well. What should I do?
