We have a 2 year old pool that has multiple cracks in the bottom and sides of the pool. Most of the cracks are long and run between the infloor cleaners. The pool company that installed the pool just drained the pool and put something in each of the cracks. Then cracks might be fixed but the stuff they used makes the cracks very obvious because it doesn't blend with the gunite color. Is there anything that can be done to make it look better?
