Calcium Removal from Pools & Outdoor Areas

Having a pool in Texas is almost a necessity with the long hot summers. Your pool is one your largest investments and you want it to look great as you enjoy a swim on those hot summer days. Over time calcium and grime will build up along the water line, over decorative rocks, waterfalls, and tile. JAC Mobile Blasting LLC has an eco-friendly process to remove the calcified residue without having to drain your pool. Our scaling removal process will not scratch your tile, compromise the grout, or damage the stonework that makes your custom pool so special. Pumice stones, scrapers, wire brushes, even acid can etch your water line resulting in expensive repairs and even possible tile replacement. Save time and your sanity by letting our team of professionals do the heavy lifting so you can enjoy your backyard oasis as it was meant to be relaxing with friends and family. Mineral deposits can be formed from sprinklers and other water sources. We can clean deposits off fountains, tombstones, monuments, statutes, rock water faces, architectural rock and other outdoor areas where water has deposited minerals. Call or email for a free estimate. Pools are custom built and therefore each job is different in nature. We typically charge by linear foot making our calcium removal a very affordable alternative vs. doing it by hand with expensive and unsafe chemicals.

The JAC Mobile Blasting Process Explained

Our team will arrive onsite to turn off the pool equipment so we can lower the water level approximately 10 to 12 inches leaving access to full water line. We prep the area by covering plants, outdoor furniture, and any other items needed before we begin the calcium scale removal process. The media we use is eco-friendly and safe for humans and pets. We use Kieserite which is blasted with compressed air ranging from 50-80 psi lifting the calcium deposit from the tile and the stone safely. Kieserite is just slightly courser than the scale builds up but not to course where it will scratch or etch ceramic and glass pool tile. After the blasting process the deck and surrounding areas are swept up and blown clear of and media over spray. The area is then given a wash down removing any residual media that may embed in the porous areas. Kieserite is water soluble and will dissipate over a short period of time. To help expedite the process we will vacuum large remaining deposits from the bottom of the pool. At this point the cleaning is done, and we will ask that you fill your pool back to normal level. You will not want to run your equipment until the pool water is above the skimmers. Failure to do this can result in damage to your equipment. You will notice the water is cloudy and they will clear up as the water settles and the filter pumps have the ability to circulate the water. The process can vary from pool to pool based on efficiency of the filter and size of the pool. Finally!!! Enjoy your backyard oasis. It may look a little cloudy, but it is perfectly safe to swim in the pool the same day we clean your pool. This will clear up in a couple of days after your system has been running. We recommend rinsing out your cartridge filter (the big filter) after a week or so.

Types of Calcium Deposits

Calcium
Carbonate Scale

This is the most common type of calcium deposit and is often seen as a white, chalky buildup on pool surfaces. It can form on pool tiles, equipment, and even pool walls. Calcium carbonate scale forms when the pool's pH and alkalinity levels are too high, leading to excess calcium in the water.

Calcium Silicate

This type of calcium deposit is less common than the calcium carbonate scale but can still be problematic. Calcium silicate forms when calcium combines with silica, which is present in many pool water sources. It typically appears as a gray or brownish discoloration on pool surfaces.

Calcium Sulfate

Also known as gypsum, this type of calcium deposit forms when calcium combines with sulfate, which is present in many pool water sources. It can appear as a crusty, white, or grayish buildup on pool surfaces. Calcium sulfate is often seen in areas with hard water.

Efflorescence

This type of calcium deposit forms on grout or mortar between pool tiles. It can appear as a white, powdery substance and is caused by moisture moving through the grout, bringing dissolved calcium with it.

How to Prevent Calcium Deposits?

Preventing calcium deposits from forming on pool tiles is the best way to avoid the headache of removing them later. Here are the tips to help you prevent calcium buildup in your pool:

Water Chemistry

Keeping the water chemistry in balance is crucial to preventing calcium deposits. Ensure the pH levels stay between 7.4 and 7.6 and alkalinity levels between 80 and 120 ppm. High calcium hardness levels can contribute to scaling, so keeping them in check is important.

Regular Maintenance

Regular maintenance is key to preventing calcium deposits from forming in the first place. This includes brushing the pool walls and floors at least once a week to prevent debris from settling and causing scaling.

Use a Stain and Scale Inhibitor

Adding a stain and scale inhibitor to your pool water can aid in preventing the formation of calcium deposits. These products work by preventing minerals from forming into solids that can adhere to pool surfaces.

Control Calcium Levels

It's important to monitor the calcium hardness levels in your pool water regularly. If the levels are too high, you can use a pool water softener to bring them down.

Use a Sequestering Agent

Sequestering agents can help prevent calcium buildup by binding to minerals and keeping them in suspension in the water rather than allowing them to settle on pool surfaces.

Regular Cleaning

Regular cleaning of your pool equipment can also help prevent calcium deposits. Calcium can build up on pool equipment, such as pumps and filters, which can then contribute to scaling in the pool.
