    Biologica Spa Alchemy™ in 500ml bottles
    Biologica Spa Alchemy - Natural Spa Cleaner

    Spa Alchemy™ is a game-changer in natural water treatment

    It works on your spa’s ecological environment to keep the water fresh, clear, and in balance longer. Yes, we know it sounds too good to be true – that’s why we called it Spa Alchemy™, and that’s why we offer you a ‘no hassle’ 90-day money-back guarantee.

    I have been using this product for 18 months in our Spa Pool. It is simple to administer; 4-6 weeks is an easy time to remember. I like the idea it’s a natural product.

    Clears spa water and keeps it clean.

    Beautiful, pure and crystal-clear spa water has never been so easy to achieve. Spa Alchemy™ works on your spa water’s ecological environment, so you don’t have to.

    The end result really is “crystal clear”.

    Balances the spa to pH neutral.

    If pH is too high you’ve build-up on the waterline, cloudy and dull water, and unpleasant skin irritations. Too low, it causes corrosion of your spa equipment shortening their lifespan and effectiveness. Spa Alchemy™ helps you get the balance just right.

    Oxygenates the water.

    Oxygen is known as a ‘natural cleanser’. The micro-bubbles it creates are negatively charged, attracting all positively charged contaminants in your water, resulting in an even higher level of detoxification and hydration.

    Natural.

    Spa Alchemy™ is a natural product. Made from plant-derived ingredients using the latest breakthroughs in natural water science. It’s totally free from harmful toxins and harsh chemicals. Use with confidence, we know it ‘naturally works’.

    Best product we have found - makes the spa fun and easy.

    EASY to use.

    Simply add 100 mills of Spa Alchemy™ for every 1,000 litres of water in your spa. Just pour it in and run your spa jets for 20 minutes. That’s it. How simple is that?

    With no chemistry degree, slide-rule or elemental table anywhere in sight.

    *4 - 6 week treatment.

    In ideal conditions it works for 4 to 6 weeks (some cases longer). A single dose every month and you’re on your way to reducing time required to keep your spa pool water in balance, clear, beautiful, pure and inviting.
    *For safety we recommend a weekly shock-dose of chlorine, bromine or hydrogen peroxide.

    Eliminates fluctuations in pool chemistry.

    It was a happy accident to discover Spa Alchemy™ has a continual and positive ongoing effect on your spa pool water. When in regular use it helps maintain your levels and effectively removes those frustrating, wild variations. One more (unexpected) positive of using Spa Alchemy™.

    Cost effective.

    Spa Alchemy™ is not the cheapest water treatment available. But, with NO additional (daily) pump circulation and a single dose lasting around a month, it works out as a very cost effective option in the long term. By actively reducing your chemical usage it's the 'natural' economical choice.

    My wife is VERY allergic to chlorine... 5 minutes in the pool is too long. Using Spa Alchemy has completely alleviated that problem.

    Tips for best results

    Regularly clean the filters thoroughly with a filter cleaner and rinse well to remove any residue. You could also use some pipe and surface cleaner to clean the inside surfaces and pipes of your spa.

    A drain and refill after thorough cleaning will also reset your spa water chemistry and allow Spa Alchemy™ water treatment to do its job better.
