Calcium In Swimming Pools: What To Do And When It Could Be A Sign Of A Larger Issue
You’re hosting a get-together in your backyard.
Invites sent. House cleaned up. Chairs and tables set out. TV is tuned to the latest Cowboys game or other local entertainment.
Your backyard is perfect – until you take a look over at your pool and notice something off: calcium build up and white nodules floating in your pool.
It’s not bad, but you mentally jot that down to get it fixed.
Your event passes, weeks and months go by and now your small calcium problem has become a larger issue – one with considerably more expensive fixes.
About Calcium Build-Up & Nodules
You can learn more about the exact details from calcium build up here, but to put it in a few words, it’s the result of a combination of items around your pool.
A combination of poor pH balance, high calcium hardness and other maintenance related tasks can often be the source of calcium build up.
The source of the calcium “nodules” can actually be from your plaster — air trapped in your plaster and little cracks form. Water rushes into those cracks, mixes in with plaster materials and eventual little pea-sized pods of calcium develop.
Nodules Are The Larger Problem
Because of the way pool nodules form – from issues with your plaster – they represent the larger concern.
Small amounts may not be an issue – but if they are becoming more frequent over time and show up in many different areas around your pool, it’s likely a sign that a replastering project may need to be scheduled in the near future.
If nodules keep forming after cleaning up, there is no great way to patch these or adjust your pool pH level – the pool plaster needs to be replaced and cured properly.
Consult A Pool Replastering Contractor
Determining if your pool needs to be replastered due to calcium build up can be challenging for many pool owners.
There are dozens of online resources to scan through, but to be absolutely sure have a local pool replastering expert take a look at your pool.
You won’t always need to replaster – a proper pool contractor will let you know if this is the case, but if you do, they’ll be able to point you in the right direction to getting that cleaned up.
Planning events around your backyard pool area should be a fun activity – not one where you have to plan around your calcium build up.
