Pool Water Green Cloudy/ Algea?

Question

Im in Arizona its hot but we also get monsoons .. after the rain the pool water turned cloudy and green ( I was still keeping up the chem. in the pool) Well I added Pool Shock and Adjusted the PH levels the water is perfectly fine chem wise but the green and cloudy look wont go away. I even took a poly/nylon scrub brush and scrubbed all the pool walls and bottom to loosen any algea .. its still the same. Again the chemicals are fine when I test the water.

Can anyone reccomend a chemical that will clear the water and the green that has actually USED it please, I don't want bottomless info I want someone who has used the product before.

Its a large in ground pool lima bean shape. Thanks

Answer 1

Simply change the sand in the filter.If the algae is in the sand you will never get the water clear.Two years is too long.Change it every spring.

Answer 2

Your filter system may not be working properly.  You may want to  put in new filters that are top quality as tiny particles can still pass through.  After the fires in CA last year we had to replace the filters twice to actually get the pool clean and clear again.  We also had to get an extra floor filter vacuum thing that scoots around the bottom attached to a hose (sorry I forget what it is called).  Our local pool supply store was happy to help us.  Good luck.

Answer 3

Backwash cycle can gradually cause filter media (sand) loss; check level in filter and add if necessary.  You don't have to change it.  Keep your filter system constantly running.

The pH level is a secondary problem.  First shock / super-chlorinate - this is paramount.  Then adjust pH, calcium hardness and total alkalinity levels.

This process can take 2-3 days depending on how aggressive the algae bloom.

If this process does not improve pool clarity you may have to add 'flock' to the pool and then change your filter sand.  Consult pool dealer for details.

There is no easy or quick fix.  Heat and bather load can dramatically effect a pools chemistry.

Answer 4

put 16oz of algacide in it to kill the alga once you get alga it would take a ton of chorine to kill it use the algacide
