Excesive algae problems may be caused by your yard! Lawn and garden fertilization, especially when applied in a liquid form. When added to the water by wind or surface run-off, these nutrients feed algae and accelerate its growth
this type of algae is one of the most difficult varieties to control and eliminate. This algae can appear as a blackish discoloration or a tar-like deposit. In either case, it is a problem to remove because of the physical nature of this algae. It has, as its outermost surface, an “egg shell” feel to it. Remove by shocking and using a good polyquat algaecide. also brush the surface area.
this type of algae is the most common and is best treated by shocking. If it reappears at a later date have your water tested for nitrates.
Mustard algae usually appears as a yellowish-greenish-brownish powdery deposit on the pool walls or bottom is usually caused by high levels of phosphates.
pink algae is not really algae but a bacterial slime. A good silver algaecide and superchlorination should do the trick
P.H is most important in water balancing and should be kept between 7.2-7.6. Alkalinity is the important base which keeps PH manageable.
Salt systems, that generate chlorine, and liquid chlorine have a high Ph and require more muriatic acid than other forms of purification to keep it in check.
Alkalinity can be increased by using sodium bicarbonate or baking soda. the ideal range is 80-100 ppm
the presence of this metal can be responsible for orange to red or rust colored stains. The most common sources of iron are from rusty well pipes or from old steel plumbing either in the house or from the city water line.
