How to Use in a Wood Fired Hot Tub

1. After cleaning and refilling your hot tub, add 2 eco3spa Step 3 – Water Sanitiser Tablets to the water.
2. Place the tablets into a floating tablet dispenser or tablet float.
3. Allow 10–15 minutes for the tablets to dissolve before using the tub.
4. Before each hot tub use, add 1 additional tablet using the dispenser.

When the Tub Is Not in Use

To help keep water fresh and sanitised, dissolve 2 tablets per week in the water using the floating dispenser, even when the tub is not being used regularly.

If the water becomes cloudy, dull or foamy, add an extra tablet daily until the water returns to normal clarity.

How to Use in Electric Hot Tubs & Spas

1. Add 2 sanitiser tablets after cleaning and refilling the hot tub.
2. Prior to each use, add 1 additional tablet.
3. For best results, place the tablets directly into the filter compartment where water circulation is strongest.
4. Alternatively, use a floating dispenser and allow a few minutes for the tablets to dissolve before entering the water.
5. If the spa is not being used regularly, add at least 2 tablets per week to maintain water sanitisation.

If the water becomes dull or foamy, add an additional tablet daily until the problem subsides.

Please note: These tablets are designed to be used in conjunction with eco3spa Step 2 – Water Conditioner and not as a standalone treatment.
