If you have a sand filter, algae can grow inside the tank. Even if you shock the pool water and backwash, the algae will not "die" inside the filter tank.

To completely get rid of algae in a sand filter, you will need to remove all the sand from the filter. Then break the internal parts apart, soak them in a 4:1 bleach water mixture,1 part bleach. You may want to wipe the parts off with a towel, or something, to remove all the algae. You will also need to scrub out the inside of the tank with more bleach water.

Once this is finished, you will need to replace the sand with brand new sand and reassemble the filter. This is the only way to completely remove algae from a sand filter.

DE filter? If so then you need to give the filter an acid bath to purge the dead alge from the filter (Fingers, Grids or Discs). Go with 1part muriatic acid to 3 part water. Let soak overnight. The water should turn almost neon green.Rinse off and reassemble. SHould be Good to go. DE and Cartridge filters should be given an acid bath once a year.

I have a sand filter and my levels say ideal but water is real cloudy after adding chlorine


Take a sample to a pool shop and find out. If the pool has been green you may have dead algae floating around, a sand filter will never take that out. You need to flock it or new water. Then there is the toy you call a sand filter, OK when everything is perfect but small filters and pumps just won't handle a very dirty pool.

Get a pool brush and brush your pool daily with it. Make sure your Chlorine level is at least 5 (I would like to see it at 10). Add dry chlorine to yor ool if you have to to get it to this level.

Alternatively, brush the sides and bottom daily with a hand brush. Keep the filter tunning until the algae is gone.

I HAVE SMALL BUGS IN THE LINE. i CAN FLUSH THEM OUT. I HAVE USED CLEANERS AND DRAIN CLEANERS, ETC.,BUT THEY RETURN. HOW DO I GET THEM OUT PERMANTLY?


Pam,

I work for a chemical distribution company with a service dept. for spa repairs and the like. When we come across this, what we need to do is super chlorinate the spa for 24-48 hours.

Using a granular chlorine (dichlor or calcium hypochlorite, or just bleach) raise the level of free chlorine to 10-15 parts per million. Most resedential test kits will not test this high so you might need to purchase test strips. Keep the level this high (it will go down quickly with parasites and algae involved) for at least 24 hours. This will kill the pests and any related waterbourne diseases.
Keep the hot tub running on normal mode for the whole period. This will flush out the system. You may need to do this multiple times depending on the severity of the situation. If you need further help just e-mail me @ adamh@newconceptchem.com. There are products that will help, but they are expensive and do essentially the same thing that i am recommending.

If this helped, please take the time to vote positively for me on this site. Thanks,

Adam

Chlorine generator not working(brand new)


Super shock your pool ... take it to around 20 ppm CL using liquid or powdered CL. Brush your pool daily for several days ... run your filter at least 16 hours a day ... 24/7 would be better. Maintain 5 ppm CL and brush weekly after you get the algae under control.

CLOUDY WATER


I too have this problem after treatment for algae, especially if I got a day or two without running the pump, it starts to get mildly green. After adding the algaecide, it kills the algae, but leaves what I call the white dead floating...it takes several days for this to phase out.

If you aren't already doing so, put 3" tablets in the pump basket housing, that helps dramatically. Put a pair of knee-high pantyhose (one inside the other), on the return inside the pool. (you will be amazed what it catches after a few days). Also you can try some "clarifier" to help clear up the cloudiness.

I'm no pool expert, but have dealt with the cloudiness myself. Through trial and error, have learned that cloudy water doesn't necessary mean dirty water. It will clear within a day or two if you are keeping stabilizer tablets in pump basket and using shock once a week. And run the pump for about 8-12 hours a day, it will clear up quicker. And to me, using the pantyhose is an extra-filter and it catches the 'gunk' that the sand in the filter isn't catching. (it can't possibly get everything). Be sure to backwash your pump frequently too.

Hope this helps at least some. Good luck!

Algacide?


I think he meant not to MIX them. Don't put them in together.

If your water is still green, it definitely needs algaecide. Be sure you get the bottle that says it will KILL algae, not the preventative. (only difference is the concentration of the product.....preventative is diluted more).

After adding the algaecide you will have cloudy water looking like very very tiny white things floating in your water. Buy a bottle of clarifier to help solve this issue. It will allow the 'dead algae' white stuff to clump together and be vacuumed up. Water will be clean and clear in no time!

Hope this helps. Good luck!

The brown-green gunk sounds like algae. You stated that you have cleaned the filter. Have you taken the cartridge completely out? If not, I would suggest that you do so. Scrub the inside of the filter tank with a 4:1 bleach water mixture, only 1 part bleach. Then soak the cartridge in an acid bath, like Muriatic Acid. This will kill any algae that is in the filter itself.

You may need to vaccuum your pool to waste, get rid of some of the water and refill it. This may help get the chemicals in order.

Another idea would be to run the system continuously for a couple of days. Vaccuum to waste, not to return lines, and clean the filter when it reaches 8 to 10 PSI above start-up. You may not be running the pump long enough to properly filter water. Keep trying to get chemicals in order.
