White residue on pool tile

Postby all4him » Fri 18 May, 2007 07:27

I have a white residue or buildup on the tile along the water line.

I have used a diluted acid mixture in the past to get rid of it but I do not want to keep using acid becuase eventually I am affraid it will eat out the groute.

Is there something a can buy to put in the water to prevent this white film or residue from forming? Or is there something available to spray on it to remove it other than an acid mixture?

Have your water tested, it may be high in pH and alkalinity, thus depositing calcium carbonate.

I did have it tested and the Alkalinity was ok but the PH was up.

What is the best way to get rid of the white residue?

If it's calcium carbonate, simply dropping the pH to 7.0 or thereabouts should make it disappear. (Technically it will go back in solution).

If you have a water heater it's important you get this under control before it clogs up the pipes.

BTW what's the average pool water temperature in Texas for this time of year?

Over here the pool's a refreshing 53 F.

Right now it is around 80 degrees. We have already been in it this year a couple of times.
