Calcium Deposits?

[PatL34]

Start using some regular bleach or even shock to help the CL move up and calcium hardness to go up slightly. The SWC does not have to be increased, just adding more bleach will save on cell life.

The CYA at 40 ppm could be increased slightly up to 60 ppm.

Use Muriatic acid to keep at 7.2 -7.6 pH and no higher.

Follwing these initial rules will help to start removing the Calcium deposits. If the TA starts to rise start some aeration to help bring it down.

Hope this helps and keep us posted.

I have been maintaining a pH of 7.2-7.4 and I see no sign of the deposits "dissolving." If keeping a pH of 7.2-7.4 will remove the deposits, how long do you think it will be before I start to notice the deposits disappearing? I have someone on my case daily because of these deposits and I keep telling her it may take as long for the deposits to disappear as it did for them to appear. Of course, this person wants instant results.

Any other suggestions or input?

My expectation is that it will take awhile and to keep up with the brushing. I'll bet they loosen up and finally flake off.

I had the same problem and it took about three weeks to completely clear up. I had some scale on my tile bad enough that I needed to drop the water level and clean it off with acid.

I'm not going to let the ph stay high this coming winter - it's just too much of a mess.

I need to tackle scaling on the tile next. Oddly, it is only in a few areas that do not even touch the water. What kind of acid did you use?
