Steps to Take for a Hot Tub Drain and Fresh Fill Using the Mineraluxe system

Saturation Index is an overall measure of water balance. The acceptable range is -.5 to +.5. Outside this range can lead to corrosion or scale-formation. Follow the detailed instructions below for a hot tub drain and refill to correct any individual water balance issues and/or resolve other hot tub water problems. Be sure to read product label directions carefully before using any recommended product.

Step 1: Clean your filter

It is recommended to deep cleanse your filter cartridge with Mineraluxe FILTER REVIVE. Prepare a solution of Filter Revive in hot water and soak your cartridge for 6 – 12 hours. Rinse well with water following soaking. If possible, allow to dry before putting back in use.

Step 2: Clean hot tub plumbing

With your filter removed, apply Mineraluxe Cleanse & Drain in the existing hot tub water 24 – 48 hours before draining.  Add 750ml of product to hot tub.  Leave the high speed jets on for approximately 5 minutes, with aeration off, 2 – 3 times during the 24 – 48 hour period.  Allow tub to run though its regular circulation cycles. Drain tub.  Mineraluxe Cleanse & Drain cleans where you can’t.

Note: Foaming is a result of the product deep cleaning built up scum within your plumbing, this is normal.

Step 3: Add 2 Mineraluxe CUBE(S) initially

To prevent staining, scale and biofilm formation from damaging your hot tub and for the most luxurious feeling water, use Mineraluxe CUBE at the recommended dosage rate with each fresh fill. Add the recommended number of Cubes directly to the skimmer basket or place in an area where this is rapid water movement and as close to a suction inlet to the filter as possible. Always apply with the high speed pump in operation. If all the Cube components do not dissolve initially, move any undissolved components of the Cube into an area of high suction so they will be carried to the filter. Use Mineraluxe CUBE on a weekly basis thereafter for continued protection.

Step 4: Add 1 pouch(es) of Mineraluxe OXYGEN

Mineraluxe OXYGEN can be added immediately after the application of Mineraluxe Cubes to the hot tub water. Leave the high speed jets on for approximately 15 minutes to thoroughly disperse the Oxygen throughout the tub. Leave the cover off for minimum 15 minutes following application for best results.

Step 5: Balance Water

Bring in a hot tub water sample to Aqua-Tech’s amazing water lab. In less than an hour, Aqua-Tech’s skilled water care experts can guide you and help you understand exactly what your water test indicates. We’ll also offer a thorough consultation to help you avoid future water problems. Finally, we’ll provide you with an easy to follow and straightforward set of instructions to get and keep your water crystal clear and balanced.

Step 6: Use Mineraluxe BROMINE TABLETS

Begin your sanitation program by applying slow-dissolving Mineraluxe BROMINE TABLETS to a floater or other bromine dispensing device. Set the output of the floater or device to maintain 3 – 5 ppm of bromine in the water at all times for maximum protection of bathers. Use Test Strips or another valid testing method to ensure the bromine level and pH (7.4 – 7.6) are within desired ranges. The Mineraluxe System has the ability to significantly reduce the amount of bromine required to maintain 3 – 5 ppm. Therefore, it is recommended that the hot tub water be tested frequently, especially for the first few weeks, so you can accurately determine the number of tablets required to maintain your water within the desired range.

    I am wondering if you can help me out. We draw our water from our well and it is very high in iron and other minerals. So bad that it turns our water brown when we add bromine. It usually takes some time before it filters out and the water is clear again. Our ph level is also through the roof. I have been looking at the Mineraluxe product and was wondering if it would work for me.

      Hi Angela:
      Minerlauxe is an amazing product for water like yours that is high in minerals and metals.
      We would love to do a source water sample test for you before you fill your spa next so we can give the most accurate advice on the best method to precent the challenge you are dealing with

    I use the mineraluxe bromine system in my hot tub – the tub size is 950 litres.
    Once per week I add one mineraluxe cube, one pack mineraluxe oxygen & add new bromine tablets to the floater (keep floater set at “4”).

    We use our tub a lot (once per day, up to 4 people, up to 1 hour) and with this much use – the above treatment doesn’t deliver enough bromine for the week. Testing the water indicates after a couple days, there is no / very little free bromine remaining (less than 1 ppm).

    How do you recommend keeping the bromine between the recommended 3-5 ppm range? Can I add Mineraluxe Brominating Granules after use, to keep up the free bromine?

    • Aqua Tech


      Hi Lindsey,

      Yes we recommend using bromine granules along with the bromine tablets! Bromine tablets are great for maintaining a good level of bromine but granules establish that level as needed! Using 2-4 teaspoons before use if the bromine is low and waiting 15 minutes before getting in, as well as using that dose of granules after use, especially if you’ve had a lot of people in there 🙂

    I used the Mineraluxe Cleanse and Drain as indicated and after draining, wiping down (with a mixture of vinegar and water) and refilling the hot tub the water is clear but it still creates a fair amount of foam when the jets are on. Is this normal? Will it go away soon? The only thing I’ve added is chlorine, and I haven’t adjusted the ph yet (it needs to have the alkalinity decreased a bit) because I didn’t know if there was something I should do about the foaming first. I don’t want to use the hot tub until I understand what’s happening. Thank you

      Hi Rhonda!
      The best way to go about this is to bring in a water test to Aqua-Tech to get a better idea of what’s going on that could be causing the foam! Since it’s a fresh fill, balancing it should help with the foam. Making sure you rinse your filter every 7-14 days and chemically cleaning the filter every 6-8 weeks is also vital to help prevent foam!
