Maybe a little kid pooped a them or it is so people can see them
Depending on the surrounds, perhaps the feet of the people getting into the pool are bringing in dirt, stain or oils they have picked up before getting into the pool. Another issue may be that the material of the steps is porous enough to grow algae.
Pool steps can be made of concrete or fiberglass, depending on the construction and size of your pool. Contact a local pool service about the steps. If your pool is properly maintained, there should be no reason to clean the steps. There should be no algae or anything else accumulating on any surface, so do get some professional advice..
It is possible to get steps that can be put into any existing pool
How do yo resurface or replaster and old pool
The best design for a brown house with a pool would be a detached deck. This is a perfect combination because the fact that a detached deck has steps, the pool could be located inside and they would compliment each other.
I do think that you need to change the Filter. It not suppose to be brown. You can buy them at any pool store in your area or retail store that sells pools.
Drain pool and clean with muriatic acid
No, because fiberglass can make you slip unlike concrete steps
Usually there is a ladder on the side, or steps leading down into the pool. Enter that way and you'll be safe. :)
There are kits available for fixing fiberglass steps that are pulling away from the pool. You will need to drain the water below the area where you will be working.
What is the best way to get rid of rough spots on pool steps??
Yes just add another coat with the sand in it. Head to your local pool supply store and ask for the treads that stick on the steps. You may have to drain the pool down a bit to get them on.
