Weekly dosage for 1200l tbb?

Hi,

I have a Cal Coop 371 tub that has a listed volume of 1200 litres. We use Mineraluxe cubes, Oxygen and bromine in a floater.

The dealer instructed me to use two cubes plus one pouch of Oxygen on start-up and then one each weekly for maintenance. We use the tub infrequently (2-4 times a week for 2 people), but infrequently the load is much more if we have guests and I shock using bromine.

In reading some of the comments here, you're suggesting that a cube each week may be too much for 1000 liters or less... While we're not having any problems I am starting to notice some sensitivity to chemicals in the form of a rash on my legs.

Can you please help out with the correct dosage or more detailed guidelines for care using your products?

Thanks,
Jeff

    Hi Jeff,

    Thanks for your message.  The guidelines for use with Mineraluxe are as you described.  In volumes of water less then 1000L, the application needs to be spread out as a single Cube is designed to treat volumes up to 2000L.  In your case, a tub with 1200L and moderate to low use may need the dosage spread out as well.  

    The way to determine if you need to adjust the frequency of product additions is with the water quality.  If you find the water has excessive froth and takes some time to disipate once the high speed is turned off, I'd recommend adding your products every 10-14 days.  However, if the water quality is good (crystal clear, little to no froth, no odours), then your  frequency of additions is probably spot on.

    If you find you are getting rashes after using the hot tub, there are a few things I would recommend:
    1. Make sure you have a proper bromine reading.  Bromine levels below 3ppm may allow bacteria and other micro-organisms to grow. Levels above 5ppm can be irritating to skin, eyes and nose.
    2. Make sure your water balance is correct.  Imbalance of pH, alkalinity and hardness can cause the water to be uncomfortable leading to irritations and rashes.
    3. Speak to your doctor about any possible allergies.  There are some homeowners that are sensitive or allergic to certain additives in water treatment products.  We are happy to let you know if any of our products contain those things you may be sensitive/allergic to.

    I hope this information is helpful.  If you have any other questions, please feel free to contact us.
