Prevention of Brown, Green and Mustard Algae
Thunderbird Pool's system of chemical care guarantees a
crystal clear, algae free pool. However, occasionally one of our pools will
experience yellow algae.
WHY?
There
are five primary reasons for yellow algae:
- Yellow algae can develop when no chlorine is present. For example, when the
spa portion ofa pool is heated, the chlorine will often be completely used up.
If the circulat~on is not immediately restored from the pool to the spa, the spa
will remam without chlorine and algae can form.
- Yellow algae thrives in shade. Accordingly, a pool cover which is seldom
removed can provide a challenging environment to prevent algae.
- Yellow algae can build up a resistance to chlorine and may occasionally
require an algaecide to eliminate and prevent its growth.
- Inadequate filtration - either from filtering too short a time period OR
filtenng with a dirty filter can spawn yellow algae.
- Most strains of yellow algae are introduced via an airborne spore that is
especially prevalent during rainy seasons. It is therefore most common to see
this type of algae immediately after rains.
WHAT CAN YOU DO TO PREVENT YELLOW
ALGAE?
- Immediately after using the spa, turn the valves so that the pool water
will flow into the spa for 20 minutes thus - rechlorinating the spa.
- Remove your pool cover one day per week to allow the water to "breathe".
- Call Thunderbird Pool immediately if you ever see any yellow algae so that
we can take any additional needed steps.
- Make sure that you are filtering an adequate number of hours for the
appropriate season. (Winter 3-4 hours, summer 7-12 hours). Also, make sure your
filter is clean and your return lines have strong water now.
- After chemical corrections, brushing the dead algae from the walls assists
the filter in removing the dead algae bodies.
IN SUMMARY
Although yellow algae is
approximately 90 percent preventable, it is 100 percent curable.
