TEST BROMINE WEEKLY
We recommend that you test the level of bromine in your water
at least weekly to ensure that you have an adequate residual
of bromine (3-5 PPM). Excessive levels of bromine (over 10
PPM) can cause corrosion.
BiO2 also produces oxygen as a powerful oxidizer to destroy
organics in the water. There is no test required for oxygen.
TEST pH WEEKLY
The pH (relative alkalinity or acidity) will tend to rise over
time and should be adjusted if pH climbs over 7.8. Any pH
lowering product may be used. High levels of bromine may
affect the pH indicator. If your test turns the water test
sample a purplish colour, check the bromine level and take a
water sample to your dealer.
TEST TOTAL ALKALINITY MONTHLY
Test strip kits are available that will indicate the
alkalinity of your spa water. Ask your spa dealer.
HARD WATER
If the water in your area is hard (high levels of calcium)
BiO2 may deposit some white flakes on the floor of the spa.
This is normal. BiO2 is actually removing hardness from the
spa water. This process can continue for a period of weeks or
months depending on the hardness level. An optional strainer
(calcium trap) will be available which attaches onto the wall
fitting. It will capture the scale which you can then
conveniently dispose of. If the water in your area is soft,
(below 120 PPM hardness as calcium carbonate) you will need to
add calcium to your water. Call your dealer or the BiO2
Consumer Help Desk for information.
REMOVING BiO2 FOR SERVICE
If you need to remove your BiO2 unit, Cover the BiO2 wall
fitting with plastic wrap and stretch a rubber band around the
wall fitting edge as shown by illustration. This is for
TEMPORARY USE ONLY. Remove the BiO2 unit from the wall fitting
tubing and apply the drain plugs to the tubing. Once the
servicing has been completed and the tubing reconnected to the
cell, the plastic wrap may be removed.
