A pink or purple ring around the pool could be caused by minerals. You should try shocking your pool water.
Condes crystals
same color as a regular pool - blue
really purple but looks blue
Is the water rusty color? Or is the rust color on the pool finish - plaster or vinyl or fiberglass?
Green
Probabily the ground surrounding your pool if its in-ground. In an above-ground pool they most likely fly into the pool or crawl into it from the sides.
look for water coming out of the pool? after you find water on the outside of the pool take a red food color on the inside ans squeeze it in the area and when you see the color being sucked to the wall and disappear there it is and you can get a under water pool patch kit at home depot for about 6 dollars.... Hope this helps you out
how do u stop the water from coming out the sides of the pool
Try green or yellow-green. Water is colorless, so any color tiles you have in your pool will make the water appear to be the same color from above. Reflections also influence the color, depending on how you view the water's surface.
The pool water draws its color from the liner. If you buy a white liner, then the pool water will not be blue. If you use a light blue liner, then the pool will be light blue. In my opinion, the best liner is a darker blue liner with ripples on it. Your pool will look gorgeous and inviting and the ripple effect makes it difficult to see any dirt in your pool. A solid color liner lets you see everything, which isn't always pretty.
Pool water and hair color often equal disaster. Best to wait until after pool season to color. The bleach used in pools will lighten your hair in most cases. Unfortunately, chemicals i the pool water can build up on your hair. Best to get a treatment to remove these before getting a new color.
Not exactly sure if this is the problem, but from my experience in the pool business I've seen purple build up on fiber glass pool's surface, and it seemed to be a combination of two or more of these conditions: low calcium, low ph, and well water
It is normal for the sides to bow to the middle of the pool, as the pool fills the sides will right themselves by the weight of the water, it happened to me but it is normal.
