How to prevent Algae:
- Practice good chemistry maintenance. Keep the water balanced.
- Keep the pool clean with regular vacuuming. Brush the walls,
paying particular attention to corners, steps and light niches.
- Maintain a clean filter and keep it running as long as
possible, particularly during hot weather.
- Use algaecide weekly as a preventative measure.
Sometimes known as blue-green algae, it appears in pools as
sporadically scattered black splotches and has become the bane of the service industry. This strain attaches itself to pool walls (primarily plaster) and sends roots deep into the finish.
Couple that with the fact that it has a slippery, protective, gelatinous sheath making it highly impervious to chemical treatment, and you have a formidable foe. This insidious strain can
resist most chlorine shock treatment (surviving even 40 ppm, well beyond mush shock treatments) and holds its own against most algaecides. The best way to deal with black algae involves a
combination of chemicals and elbow grease. You will have to scrape and brush hard to remove the protective sheath and leave it vulnerable to chlorine. Use Bio Guard Algae All 60.
Probably the most common kind of algae, this, too, sports a
gelatinous sheath protecting it from most chemical attacks. Unlike black algae, it doesn't attach itself to walls, however. Green algae causes the pea-soup green water look of the neglected
pool. However, because this strain floats freely in the water, chlorine shock treatments can effectively eradicate it when used in conjunction with lots of brushing vacuuming and filter
cleaning. Make sure that the pool has plenty of circulation and filtration time as well. Use Bio Guard Banish.
This strain, also referred to as yellow algae, is a more advanced
form than green or black algae in terms of its cellular structure. It will also appear on walls and in shaded areas of the pool, but employ caution when it comes to cleaning it out. If you
attempt to brush yellow algae, it can flocculate and spread throughout the pool, making a bad problem worse. Aggressive chemical treatment can help, as well as increasing the pool's
filtration time. Numerous algaecides that specifically target mustard algae exist today. You may try several approaches until you find the one that's right for your situation. Use Bio Guard Banish.
Sometimes known as pink slime, it usually shows up at the waterline of the pool, distinguished
as a pink, orange or reddish ring around the circumference. Actually a fungus rather than an algae, it can also show up around underwater lights, ladders and other fixtures. Resistant to
chlorine, techs can best remove it by brushing and vacuuming. Use Bio Guard Back-Up.
