Think your magnesium pool can take care of itself year-round? It might be more forgiving than traditional chlorine systems, but even the best pools need a bit of seasonal TLC to stay in top shape.
Magnesium pools offer a luxurious swimming experience, with water that feels silky smooth and gentle on the skin. They’re known for their therapeutic benefits and lower maintenance demands.
But "lower" doesn’t mean "none." Each season brings its own challenges, from scorching summer sun to leaf-strewn autumn afternoons, that can affect water quality and equipment performance.
This guide walks you through how to keep your magnesium pool healthy, balanced, and sparkling through every season. You’ll learn practical tips, discover common pitfalls, and understand how a little consistency can make a big difference.
Whether you’re a new pool owner or just looking to fine-tune your maintenance routine, this seasonal care checklist will help you get it right all year round.
Magnesium Pools and Their Unique Needs
Magnesium pools stand apart from their chlorine and saltwater cousins thanks to their natural mineral content. Instead of relying solely on chemical disinfectants, they use magnesium chloride, which is a mineral known for its health benefits and gentler effect on skin and eyes.
Swimming in magnesium-rich water can feel like a spa experience. It’s softer, less irritating, and often leaves skin feeling nourished rather than dried out. Some swimmers even report relief from muscle tension and skin conditions like eczema.
While magnesium pools generally require less aggressive chemical balancing, that doesn’t mean they’re maintenance-free.
To keep the water crystal clear and comfortable, it’s essential to monitor the mineral balance, pH levels, and filtration system.
Neglecting these basics can lead to cloudy water, scaling, or even equipment strain. The secret lies in understanding the unique water chemistry and giving your pool the right attention throughout the year. When you do, the results are well worth it.
Seasonal Pool Care: What Changes Through the Year?
Each season affects your pool differently. Adjusting your maintenance routine throughout the year ensures your magnesium pool stays clean, clear, and ready for a dip, no matter the weather.
Summer
Summer puts your pool to the test. With longer days and heavier pool use, high temperatures can cause water to evaporate faster, concentrating minerals and throwing off your chemical balance.
- Check magnesium and pH levels weekly, especially after heatwaves or heavy usage
- Run your filtration system for longer periods to keep water circulating
- Use a pool cover during non-peak hours to reduce evaporation and limit UV damage
Autumn
As the leaves start to fall, so do your pool’s needs. Autumn introduces more organic debris and cooler temperatures, which can impact water balance and clarity.
- Skim leaves and debris regularly to avoid filter clogs and algae build-up
Adjust chemical dosing as temperatures drop and pool usage decreases - Clean out skimmer baskets and inspect filter cartridges more frequently
Winter
Even when the pool is not in use, winter care matters. If left unchecked, still water can become a breeding ground for algae.
- Keep the pump running for short daily cycles to maintain circulation
- Don’t assume water testing can stop, check every two to three weeks
- Add a winteriser suitable for magnesium pools to help stabilise levels
Spring
Spring signals a return to warmer weather and swimming season, making it the perfect time for a refresh.
- Test and balance water chemistry before the first swim
- Give filters and pumps a thorough clean and inspect for wear
- Look for any signs of algae or scaling and address them early
Components of Magnesium Pool Maintenance
Keeping your magnesium pool in top condition starts with regular water testing. Aim to test weekly in warmer months and fortnightly during winter.
You’re mainly checking magnesium concentration, pH levels (ideally between 7.2 and 7.6), and calcium hardness.
Filtration plays a big role too. A clean filter system ensures the mineral-rich water stays clear and free from contaminants. Make sure to rinse or replace cartridges as needed, especially after heavy rain or storms.
Adding magnesium chloride should be done gradually and only when levels are low. Overloading your pool with minerals can lead to cloudiness and even scaling on surfaces. It’s all about balance.
Circulation is key. Stagnant water encourages algae and bacteria growth, so keeping things moving, either manually or with a timer-controlled system—helps maintain clarity and prevents buildup.
Common Mistakes Pool Owners Make (And How to Avoid Them)
Relying Too Much on Automatic Systems
It’s tempting to let your pool’s automation handle everything, but even smart systems aren’t foolproof. Malfunctions can happen without warning, often going unnoticed until water turns cloudy or equipment starts acting up.
Always double-check your system’s output and run manual tests regularly.
Using the Wrong Chemicals
Not all pool chemicals work well with magnesium systems. Harsh chlorine shocks or generic algaecides can upset your pool’s mineral balance and even corrode parts of your system.
To avoid damage, stick to products specifically formulated for magnesium pools.
Ignoring the Seasons
Pool care isn’t a set-and-forget task. Each season brings new challenges, such as temperature changes, debris, and usage levels all affect your water balance. Adjusting your maintenance routine accordingly helps avoid unnecessary issues.
Skipping Winter Water Testing
Don’t skip water testing in winter just because you’re not swimming. This is when problems often develop under the radar. Regular testing, even in the off-season, keeps your water in check and saves you from a major clean-up come spring.
Staying consistent and proactive is the best way to avoid costly mistakes and keep your magnesium pool in top condition year-round.
Natural Water Balance Tips for Lasting Clarity
Keeping your magnesium pool naturally clear doesn’t have to be complicated. A few small, regular actions go a long way.
Start with regular top-ups using clean, fresh water to replace evaporation and dilute any excess mineral concentration. This keeps the overall water chemistry stable without needing constant chemical adjustments.
A good pool cover makes a big difference too. It reduces exposure to debris, rainfall, and UV rays, helping maintain water clarity while cutting down on maintenance time.
Instead of relying on big, infrequent cleans, opt for consistent weekly care. Light skimming, water checks, and circulation keep things running smoothly and reduce the risk of algae or scaling.
When magnesium is well-maintained, it not only supports water clarity but also benefits skin and muscles, making every swim feel like a luxury retreat.
When to Call in the Experts
While regular maintenance goes a long way, there are times when it’s best to bring in a professional. After storm events, heavy rainfall, or if you notice persistent cloudiness, expert servicing ensures everything gets back in balance quickly.
Seasonal servicing is especially helpful before summer hits. A full check of your filtration system, chemical balance, and magnesium levels can prevent issues during peak swimming season.
If your equipment starts making strange noises or the water just isn’t staying clear, it’s worth getting a professional to take a closer look.
Sparkling Water Starts with Consistent Care
A magnesium pool adds luxury and relaxation to any backyard, but even the best pools need smart, consistent care to stay that way. Seasonal changes, environmental factors, and day-to-day use all affect your pool’s overall health. Staying on top of routine maintenance is the key to crystal-clear water and long-term performance.
