After Heavy Rain…What to Check for in Your Swimming Pool

Here in Australia, it can rain for days or even weeks so now seems like the perfect time to talk about what to do to your pool after you have had heavy rain in your area.

Light rainfall or minor showers usually don’t have too much of an impact on your pool, however we still recommend checking your pool water chemistry either way. After heavy rains though, do yourself a favour and take a little time to correct any imbalance levels.

You might already know, and otherwise it won’t surprise you, rain can sometimes have a major effect on your pool water chemistry. Not only can the heavy rain dilute your pool water, rainwater is usually alkaline (and can even be acidic at times) which would have an effect on the pH level of your pool water.

To make sure your pool bounces back perfectly after (heavy) rainfall we have a five step guide that we recommend following:

Step 1: Clean your pool

If you have had heavy rainfall this could have been combined with winds or storms which might have blown debris and dirt in your pool. The first step is to get rid of the debris in your pool so your Bionizer (or other sanitiser), filtering and pumping system’s performance won’t be affected by this.

Check out this blog post for tips and tricks on pool maintenance and cleaning.

Step 2: Check your water level

The rain has likely caused the level of the pool water to raise. If needed, you can drain your pool by activating your filter’s ‘backwash’ setting until the pool water has reached the desired level. We recommend doing this before testing your pool water.

Step 3: Check for phosphates

Rain brings phosphates to your pool, which is food for algae. In order to prevent algae attacks, you will have to remove the phosphates. You can simply do that by adding a phosphate remover to the pool water. We recommend using our effective and super concentrated Bionizer PFP that will quickly and safely rid your pool of phosphates.

Step 4: Test the pH and total alkalinity levels in your pool water

In case of alkaline/acidic rainfall, the pH level and especially the total alkalinity level in your pool will have changed. Make sure to balance your pH and total alkalinity levels according to your pool balance snap chart before continuing to the next step.

Do you have Bionizer’s pH controller ‘pH Boss’ to monitor and balance your pH level? You will still need to test the levels and likely add some buffer or sodium bicarbonate to aid with the total alkalinity levels. With a pH Boss, however, maintaining the pH levels at the right setting will be automatically taken care of.

What about the calcium levels?
Your calcium levels shouldn’t have been affected much because of the rain. If you haven’t tested your calcium levels recently, we recommend doing it now that you are balancing your pool water anyway. Low calcium level can result in a lower copper reading than the actual copper level. It is better to be sure about your readings before adjusting the copper levels to prevent over-ionising your pool.

Step 5: Test the copper levels (or other sanitiser levels)

Now that you have balanced your pH and total alkalinity levels, it is important to check the copper ion level (or chlorine or other sanitiser levels) in your pool.

Rain often brings contaminants to your water, not just from the rain itself, but also from runoff from your pool deck or surroundings. The copper ions in your pool will work hard to get rid of these contaminants that have been introduced to your pool during rainfall or possible storms. This will probably have caused your copper levels, or any other sanitiser levels, to drop.

What to do when copper levels are down?
Are your copper levels down? Enter the measured copper level to activate the boost function on your Bionizer to increase the copper level to the desired level (page 18 of your Bionizer instructions).

Optional step 6: Oxidise the pool water

Does your pool water still look a little bit hazy or cloudy? We recommend oxidising your pool water to get rid of the hazy look. There are several methods to oxidise your pool water. The cheapest way of oxidising is adding a cup of chlorine for every 10,000 litres of pool water. Chlorine free solutions such as Potassium Monopersulphate and Hydrogen Peroxide are also very suitable. Use as per instructions on the packaging. Add the oxidiser of choice to your pool late in the day and run your pool pump for several hours. Your water should be sparkling the next morning.

Or for a potent and hands free solution, consider an Eco-Oxidizer for your pool to keep your pool water sparkling and free of contaminants that make your pool look hazy.

Do you have a chlorine pool? Instead of oxidising your pool water, shock your pool to get rid of chloramines in your pool.

After the rain, back to swimming

Now that you have brought your pool balance back to the correct levels you can go back to swimming in your nice pool. If you have followed the steps as mentioned above you won’t have any rain fall related troubles such as algae attacks or cloudy pool water.

Enjoy your pool!

Our new bionizer pool is a game changer. After 12 years as a Learn to Swim Teacher it is a treat to spend time in our pool and not smell like chlorine. The Fresh Water Pool is always inviting.
We choose a bionizer pool system to avoid the use of chemicals. It is so wonderful to eliminate harsh chemicals from our pool maintenance routine.
The support team are always available and ever helpful with any query we have as new bionizer customers.
Our family of 4 children & 3 grandchildren, all mermaids, love the beautiful bionizer pool. They spend all day in there and never stingy eyes or chlorine smells.
So pleased we made the change!

We have just been through the third winter with our pool. In January we bought a pHBoss so we now have all three devices. The pHBoss is so good that I have not had to add anything to the pool apart from one dose of buffer since late January. A completely automatic pool! Fantastic! A 31.5 degree pool and we swim in it nearly every morning around 7 am.

We highly recommend these products and this company for quality and excellent service. We have been investing in the Bionizer System for two years now and our pool has never looked better or clearer. The low maintenance required now has ensured it has already paid for itself. I am especially happy that we feel safe swimming regularly especially with my wife's medical condition and her rehab time required in pool. No more strong chlorine smell can only be a positive and good for you. You will be really happy. Do it

I use my pool every day summer and winter. I am running the Bionizer unit, Eco oxidiser and PH Boss -55,000L pool with glass filter. My pool has never look better since installing, I love that fresh water feeling. Keep your water balanced and let Bionizer do the rest, best investment I have made for our pool.

When my saltwater chlorinator failed after only 3 years, and the second saltwater cell in 3 years failed at the same time, not surprisingly my pool went as green as your front lawn! I thought there has to be something better than this so I did some online research and stumbled across Bionizer's website. I thought this sounds to good to be true. I did lots of research and spoke to Brian whose knowledge about pool water is second to none! Although it was virtually double the price than replacing the saltwater chlorinator and cell, I was attracted by the claims of the virtual eradication of chemicals and significantly less pool pump use which saves in electricity costs. I was also attracted significantly to the claims around the quality of the water with no chemicals in it and the benefits to skin and health of swimming in what would apparently be like drinking water. I bit the bullet and bought the Bionizer complete with the Eco-oxidizer and the PH Boss.

It took about 2-3 weeks, around 50 litres of liquid chlorine, a couple of phone calls and lots of advice and guidance from Brian and a lot of consistent perseverance but we eventually got the pool water balanced and cleared and now it is crystal clear. The Bionizer was installed around mid January 2021 so for the last few weeks, the pool has been clear and looking wonderful. I have done next to nothing since except test copper levels each week and ensure the water remains balanced and that's it! I've not had to do anything else and the claims are true!!

As someone who suffers from chronic urticaria (hives) and other allergies, swimming in chlorinated water was doing nothing for my skin or allergies. Now I get out of the pool and my skin is not irritated. There is no more trademark tackiness of your skin that you get with chlorinated water. This system is simply fabulous!! I am delighted with the results and would strongly recommend it to anyone who wants to kiss goodbye to all those awful chemicals, the endless trips to the pool shop for water analysis, the ever increasing costs of all the chemicals and the hours spent labouring trying to keep your pool water from going green!

Do yourself and everyone who swims in your pool a huge favour and install the Bionizer system. I'm sure you will conclude it will be one of the best decisions you ever made!!!

We first bought a Bionizer at the start of 2019 to try it and recently also bought the Eco Oxidizer to take our commitment to the next level because we were so happy with our purchase. We were astounded at how little maintenance our pool has needed since we added these quality products to the upkeep of our pool. The initial outlay has already paid for itself in full quite easily since.

Visitors even comment on how clean they feel in our pool and they love that there is no chlorine smell on their body or hair. Skin conditions like my eczema are not aggravated and my wife who has MS now feels confident to exercise daily and feel safe about spending all that time in the pool due to the health benefits of using our Bionizer. The pool always looks good and I have attached pictures for you to see for yourselves.

On a personal level the staff at this company are a pleasure to deal with, very caring and compassionate to their customers needs and give excellent service as they are very passionate about health and their products. If you are thinking of investing in these products then you will be very glad you did.
