Tubs Parts Frequently asked questions: Our products and services

How often should my spa filter be cleaned?
Your spa filter should be rinsed regularly with a garden hose or filter cleaner, once or twice a week depending on spa usage. In addition to this weekly rinse, you should perform a deep clean of your filter once a month (or more frequently if needed) by rinsing it and soaking it in a solution of water and a filter-specific cleaner to remove accumulated residues and particles.

When should I replace my spa filter?
It's time to replace your filter when the fabric shows signs of wear, it remains dirty even after rinsing, and water does not flow (or flows poorly) through it.

What is the difference between blue spa filters and white filters?
Blue "Microban" spa filters prevent bacteria buildup on the filter surface, keeping them cleaner and lasting longer than standard white filters.

What is the difference between Claralys spa filters and other brands?
Claralys filters have a honeycomb fabric that does not fray over time and captures even the smallest impurities better than generic filters. The fabric is made of spun-bond polyester, a material that prevents dirt buildup, rinses easily, and increases filter life.

Do you offer sand filters?
We do not sell sand filters.

How do I get rid of foam in my spa?
First, simply using an anti-foam product can solve the problem. The product is quick and effective, allowing you to enjoy clear water again.
If your water remains cloudy, we recommend emptying the spa (at least partially) and performing a shock treatment with chlorine. It’s also a good idea to clean your pipes at the same time.
Finally, check and adjust the pH and alkalinity levels in your spa, avoid entering the spa with cosmetic products on your skin, and rinse swimsuits thoroughly before use.

How do I treat my spa with bromine?
To treat your spa with bromine, use bromine tablets in a floating dispenser or your filter cartridge, keeping levels between 3 and 5 mg/L. For more details, check out our complete tutorial!

How do I treat my spa with chlorine?
To treat your spa with chlorine, use tablets or granules directly in the spa or pre-diluted in a bucket. Plan on 15g per cubic meter for granules or 5 effervescent tablets per cubic meter of water. For more details, consult our complete tutorial!

Why does my spa water smell bad?
The basic cause of a bad-smelling spa is always the presence of bacteria or biofilm, a thin layer of bacteria that forms on the walls and in the pipes. In the event of a bad smell, we always advise you to empty your spa by cleaning it and refilling it with clean water. For a complete guide, follow our tutorial on spa water maintenance!

Why is my spa water cloudy?
To clear cloudy (and often smelly) water, check the chemical levels: test the pH, alkalinity, and disinfectant (bromine or chlorine). Imbalance can lead to cloudy water. Clean or replace your filters: A dirty filter cannot purify the water well, so cleaning or replacement may be necessary. Use a clarifier, which helps group small particles so they are more easily filtered. Finally, tackle biofilm by cleaning the pipes with a anti-biofilm product to remove embedded bacteria.

How often should I treat my spa water?
The frequency of treatment depends on your usage (frequency of use, number of bathers) and the disinfection products used. Add disinfectant (bromine or chlorine) to your spa about once or twice a week to keep the water clean. Test the water two to three times a week and add disinfectant as needed based on the results. If the spa is heavily used, it may be necessary to test the water more frequently to maintain proper disinfectant levels.

When should I change my spa water?
You should change your spa water every three to four months. However, the frequency may vary depending on usage: if the spa is frequently used or by many people, more frequent water changes may be necessary. A good indicator is the water quality. If it becomes difficult to balance despite regular treatment, it’s time for a water change.

Why can’t I find ozonators on your website anymore?
As of July 1, 2024, a new European regulation on ozone generators is in effect: these devices are now regulated under the EU Biocidal Products Regulation and are no longer allowed to be sold within the EU. No worries, Tubs explains everything in detail and suggests ozonator replacements.

All your questions about pumps and heaters

Why is my spa not heating up?
If your spa is not heating, several issues could be at play: a problem with the sensor, flow detector, or pressure switch, a tripped breaker, a faulty pump, or even a clogged filter. Check out our tutorial for a step-by-step guide to identifying your heating problem.

How long does it take to heat a spa ?
A 1000-liter spa with a 3 kW heater and a cover in good condition will generally heat up by 1° to 2° per hour, depending on the ambient temperature and the quality of its insulation.

I can't find my pump on your site.
If you can’t find your pump on our site, it could be for a few reasons: it may no longer be manufactured, be out of stock, or we may simply not carry it. Feel free to us and send us photos of your pump so we can help identify it if necessary. We’ll do our best to find your pump or a fully compatible alternative.

Do you sell self-priming pumps?
Tubs does not sell self-priming pumps, which are more common for pools.

Do you sell three-phase pumps?
No, we do not sell three-phase pumps.

All your questions about control systems, keypads and electrical installation

Why is my spa tripping the circuit breaker?
Several causes may explain the issue: a damaged heater element, a water leak in the control system, a worn-out pump, or a defective component. Moisture or corrosion in the control box can also lead to overloads. To troubleshoot, turn off the power and disconnect each spa component (heater, pump(s), blower, ozonator, etc.) one by one, restoring power after each disconnection to identify the source. If the issue persists, please consult a professional or us.

I don't understand the error message on my spa control panel.
First, check your spa's manual for a detailed description of the message, as meanings vary by spa model. You can also restart the spa: turn off the power for a minute, then turn it back on. Often, a restart can reset temporary error messages. We've also listed common error messages that appear on spa panels along with their solutions.

Why does the FLO (or FL) message appear on my spa control panel?
This usually indicates a water flow issue. It can mean water is not circulating properly through the heater, preventing the spa from heating. Possible causes of the "FLO" message include: a clogged or blocked filter that reduces water flow, an air bubble trapped in the circulation pump line, a failed or defective circulation pump, a mispositioned valve, or a faulty flow sensor (or pressure switch) sending an incorrect signal. To resolve this, we've listed common error messages that appear on spa panels and their solutions, or feel free to us.

Why does the "Heater Dry" message appear on my spa control panel?
The "Heater Dry" message indicates that the heater in your spa detects a lack of water or low water flow, preventing safe heating. Ensure the water level is at the recommended level. A dirty filter can restrict water flow, so remove and clean it to improve circulation. Also, ensure all valves are open and that the jets are not blocked. If the message persists, it may indicate a more complex problem within the circulation system or with the heater sensors. We've listed common error messages on spa panels and their solutions, or feel free to us.

My spa control system is no longer available, what can I replace it with?
If your spa's control system is no longer manufactured or distributed, depending on the model, it may be possible to replace it with a system from the same brand without changing the control panel. Otherwise, a complete replacement of the control system and panel will be necessary. Don’t hesitate to us: we're here to help you find the ideal solution for your spa.

How to measure a spa cover?

How to measure the radius of a spa cover?
Using a measuring tape and a ruler or a square, measure the distance from the extended corner of the spa to the point where the curve of the spa’s corner first meets the edge. If in doubt, round the value down to the nearest centimeter. More details in our tutorial!
