calcium buildup

I did a complete rebuild of my pool in June. Removed the old plaster, all the tile, and the coping, and replaced it with Mini Pebble, Glass Tile, and Stamped Concrete Coping. So it is only seven months old. I tested my fill water before filling: All tests done with Taylor K-2006 June 12, 2023 -...

Update: I started following the SLAM method. Have used almost 9L liquid chlorine in 5.5 hours. Does this sound crazy ? 11am free chlorine @ 0. Added 2.8L liquid chlorine and got it >10. 2.30pm free chlorine @ 0, added 3L liquid chlorine. 3.30pm free chlorine @ 8. 4.30pm free chlorine @ 0...

Hi all, We have a 1yr old 10,000 gallon SWG fiberglass pool. I am prettty anal with water chemistry, checking and balancing every other day or so using Taylor test kit, and going by the ranges and levels suggested here and in the pool math app. Chemistry has been stable. I drained my pool...

Bear with me, this is a question with a few parts. I understand that the "proper" solution to some of those parts might be to rip something out and start again. While I respect that opinion, that's not feasible for me at the moment, so I would appreciate other options, even if they are not...

Hi, I have some growth on the tiles under and around where the water feature is. It appears to be some type of calcium buildup. I’ve tried scrubbing with a little acid but didn’t seem to remove much. Any idea what this is and how I can get rid of it? Thanks!

We just had our 30,000 pool replanted with Diamond Brite Blue Quartz 6 weeks ago. We brushed the pool like we were told to do 2 times a day fir the first week, then we were out of town for a week. Once we returned home things seemed fine. Pool looked great, but we found out the renovation crew...

Hello and Happy Spring Opening to All: I have posted about this issue before, and here we are again.....the old thread was discontinued so I'll create a new one here: I have noticed over the last four years (including recently when I opened my pool) that our "raised overflow waterfall spa"...

My calcium hardness has gotten very high (~1,200) due to my local hard water supply and three summers of evaporation. I don't want to drain and refill due to the current severe drought. Unless I want to deal with high calcium forever, I think I need to get a water softener for my autofill line...

It's been a while since I've been on here. Pool is 20x40x10ft. Short version, muriatic acid won't remove limescale, calcium deposits from pool walls. I don't know what else to try. Back story, the house we bought had been sitting for 2 years when we bought it in sep of '19. The pool was a...

New pool owner here -- just finished construction a few months ago. I'm trying to determine whether the white stains on the natural stone of the raised spa around the spillway are calcium or efflorescence. The spillway from the spa shoots into the pool, but there is some small dribbling of...

Good Morning! We had a new pool put in this summer and we had some trouble getting the chemicals right. They are all good now but I have noticed on my grey fiberglass steps when the water level gets low they are white. I think its calcium scaling but my pool builder says he has never seen this...

I balance my water every Saturday and didn't notice this last week. I saw white calcium flakes on my pool steps this morning. Near one of the returns. I pulled one out, dropped muriatic acid on it, it fizzed and bubbled so I'm assuming it's calcium. I checked the water chemistry: ph: 7.8 Alk...

Does anyone have any experience with the Broadhead H2O system? I am in the process of building a new pool & I am trying to make it as maintenance free as possible. In the past I have been very careful about checking the saturation index and adjusting things to avoid calcium buildup...

Briar here. I am deep in the process of an ascorbic acid stain removing process for my 20k IG, Indoor plaster pool. Tested the steps with ascorbic acid in sock and had some fading. I bought the house 7 years ago and the pool was in atrocious shape. A local pool co. did a pretty thorough...
