Keeping your pool water crystal clear without throwing in a heap of chemicals? Totally doable. If you want your pool to stay clean and fresh the natural way, it’s all about balance, regular care, and using simple, effective strategies. Let’s dive in.
Keep Leaves and Debris Out
First things first—stop stuff from getting in that doesn’t belong. Leaves, dirt, and bugs? They mess with pH levels and encourage algae to spread like crazy.
Here’s the easy fix:
- Use a pool cover when you’re not swimming.
- Skim the surface daily with a net (yep, every day).
- Keep nearby trees and plants trimmed back. Less debris means less maintenance.
Get the Water Moving
Stagnant water? That’s like an open invitation for bacteria and algae. Your pool pump needs to run often enough to cycle all the water through the filtration system.
- In summer, aim for at least 8 hours a day.
- In winter, half that is usually fine.
Check your pool pump settings and adjust them depending on how much the pool is being used.
If you’re unsure, local retailers like Para Pool & Spa or Pioneer Pool & Building can give you advice based on your specific setup.
Keep That Filter Clean
Your pool filter does a lot of the hard work, but it needs a rinse now and then. Think of it like a vacuum cleaner filter—if it’s clogged, it can’t do its job properly.
- If you’ve got a sand filter, backwash it every 1-2 weeks.
- Cartridge filters? Take them out and hose them down regularly.
Balance the pH (Naturally!)
Instead of dumping in harsh chemicals, try natural alternatives to balance pH levels and keep algae away.
- Baking soda keeps pH levels in check. Add a cup or two if the levels are off.
- White vinegar helps lower alkalinity without harsh chemicals.
- Borax (yep, the laundry kind) prevents algae and keeps water sparkling.
You can grab these at supermarkets or home improvement stores like Bunnings or Mitre 10 in NZ.
DIY Natural Pool Sanitiser
Chlorine is the go-to for killing bacteria, but there are some milder, natural ways to help keep your water clean:
- Saltwater pools use a salt chlorinator that produces chlorine naturally, meaning fewer chemicals.
- Hydrogen peroxide (food grade) can sanitise the water without nasties—but check with a pro before using it.
- Mineral pool systems use magnesium and natural sanitising minerals instead of heavy chlorine. Brands like MagnaPool are sold by NZ retailers like Bay Spas & Pools.
Use Natural Enzymes
Ever heard of natural enzyme treatments? They break down oils, sunscreen, and other gunk that cloud up your water. Some NZ specialty pool stores stock these, like Pool & Spa Warehouse.
A Little Bit of Vitamin C
Cloudy water? Rust stains? Crushed vitamin C tablets can clear up metal stains and keep the water looking fresh. Just sprinkle it around where needed.
Plants That Help Purify
Poolside plants aren’t just for looks. Some can actually help keep the water purer by balancing the ecosystem (especially in natural pools). Look at options like water lilies or papyrus if you’ve got a more natural setup. Head to your local garden centre like Palmers or Kings Plant Barn for advice.
Shock With the Sun
Instead of chemical shock treatments, let the sun do some of the work. Direct sunlight burns off chloramines (the nasty smell from mixed-up chlorine). Just leave the pool uncovered on a bright, sunny day to freshen things up.
Stay on Top of It
The biggest secret? Consistency. Doing small things regularly makes a huge difference.
- Skim daily
- Keep the filter clean
- Keep the water moving
- Balance pH naturally
By taking a natural approach and staying proactive, you’ll have a crystal-clear pool without drowning in chemicals. Give it a go!
