The first thing that has to be done is to clean the pool to remove as much organic debris as possible.
Algae on vinyl pool liner.
What differentiates it from algae is that it s more of a parasitic type organism says terry arko water specialist for seaklear pool spa products based in bothell wash.
Here s my recipe for turning around a dark green algae filled vinyl liner pool.
The liner being non porous resists algae growth.
Vinyl swimming pools are not restricted to standard molds like fiberglass.
To clean a vinyl pool liner you can brush wipe and vacuum it.
The red algae seems gone but the brown will not come off even after scrubing with a brush.
We treated it with a super algeacide and ph balance.
Over time the pool liner can fade or accumulate stains and dirt.
Once the algae has appeared onto a vinyl pool liner it is not hard to get rid of but it is a good indication it is time to check the pool s chemical levels.
The pool water is clean but the liner is covered it what appears to be brown and red algae.
There s no way the water will come back if you have a layer of leaves on the bottom of the pool or floating around on top.
It also prevents the growth of algae bacteria and fungus in the pool.
Once you have the algae removed be sure to maintain the pool at its proper ph and chlorine levels to prevent the algae from coming back.
