Best way to remove calcium buildup?

[Awali]

I have little white sharp crusty things all over my pool walls, bottom, and the metal parts of my lights. I believe this is calcium build up, and I need to get rid of it because my kids are scraping and cutting their feet, it’s so sharp!

I bought an aluminum brush head (this one https://www.amazon.com/dp/B0893KHMCM?ref=ppx_pop_mob_ap_share) but it wasn't strong enough to remove anything.

My best luck has been with the green scour side of a standard kitchen sponge and manually scrubbing away at it. But it’s a 50,000 gallon (plaster) pool and while I can get the walls in the shallow end, I can’t get the bottom or very much of the deep end.

What is the best way to remove these things?

Can you post your latest test results? That would others know how to advise you going forward.

These are my results from today but the calcium (or whatever it is) first appeared early last season. It is no longer increasing or appearing new…I’m just finally trying to get rid of it.

After today’s test, I added muriatic acid to reduce the pH. I didn’t test the CYA today.

Thanks!

Your fc is very low - have you tested cya recently or is it actually zero?
You wanna make sure you follow the proper
FC/CYA Levels or you will have algae on top of your scale issues.
Here’s some info on dealing with the scaling

Calcium Scaling

Calcium scale on your pool is something we all want to avoid. With some elbow grease and a pumice stone for pools we can help you remove this eyesore.

Be sure to turn on csi tracking in poolmath settings
you will need to input your cya & pool temp as well for csi to be calculated

Having the same issue. Try pumice stone brick from Leslie's or Amazon. I'm guessing you either have to use this or drain the entire pool and get it acid washed.
