Excessive calcium carbonate corrodes your pool’s metal fittings, leaving ugly white build-up and rust stains. It will also eat fittings and create pinholes on pool equipment. Sadly, these issues can escalate, leading to a bigger problem. Well, the silver lining is with proper pool maintenance, you can keep calcium in check, assuring your water remains balanced. Here’s what you need to know:

Check the Water Chemical Balance

Excess calcium in your pool is due to a chemical imbalance in the water. If your pool water’s pH level is off, the alkalinity will become affected. As a result, you can deal with cloudy water, algae growth, and calcium deposits. Hence, work hard to check your water balance to keep the pool water safe for use while preventing these harmful deposits.

Evaluate Water Temperature

Another source of excess calcium is your water temperature. Calcium is more soluble in cold water. In contrast, hot water cannot retain as much calcium, so it is more likely to leave deposits behind. For best results, you may want to scale back on your water heater to prevent these deposits.

Use the Compound in Moderation

Since calcium poses a big problem, you may be tempted to remove it from your pool water entirely. However, this can be a mistake. Though high calcium will cause cloudiness in water and equipment flakes, scales, or leaks, low calcium means the water will attack your plaster pool walls, heat exchangers, and metal fittings. The best way is to add just the right amount of calcium. If you’re not sure about this, seeking professional pool services is your best ally.

Maintain the Best Calcium Level

Just like your pH or alkaline levels, pool water calcium content requires keeping the right balance. Ideally, your pool must have a content range of 100–400 parts per million (PPM). This is indicative of how much substance is present in the water. Now, you may find yourself in two situations, such as:

l Raise Hardness

If you don’t have enough calcium in your water, you can add a water hardener to increase the calcium levels. Pails of granular hardness increaser are readily available in any swimming pool store.

l Lower Hardness

Should you have excessive calcium in your pool water, you must use a sequestering agent. This treatment will effectively fight high metal and calcium content. As a bonus: it works well in fighting pool stains. If you live in a region with hard water, this water softener must become a regular part of your pool maintenance regimen.

Seek Professional Advice

If you feel like a fish out of water dealing with all these complicated concepts, seeking help from your local pool professional is offers the best solution. They can help you with calcium problems and prescribe a pool maintenance plan to ensure your water stays healthy. You will receive true value for money as your pool waters stay healthy and safe for everyone. With professional pool maintenance and services, you can also prevent major problems that cost a lot to repair.
