The pool and this great forum are both new to me. Hope my question hasn't been answered already. If it has, I missed it. I've read quite a bit on the forum and hope to be an expert soon!
Our pool was just installed this year and I guess I'm still working on getting everything adjusted just right. The problem that I'm having is stains on the fiberglass. There are several stains that are on the walls and floor of the pool that are round. There is also some discoloration on the steps in the shallow end. All the stains are light brownish or dull yellowish in color. More of a discoloration than a color. The sides of the pool are mostly covered in a layer of dirt that is almost impossible to brush off but I keep working on that with the brush, a sponge mop and Soft Scrub. I also have a dirt ring around the water line almost all the time. As soon as I clean it off, a few hours later it returns. I'm really asking for help (at least now) with the staining and am giving the other info in case it offers any helpful clues. We had several inches of rain today and when I vaccuumed tonight, I THINK the staining is worse.
The pool is white fiberglass San Juan. It was filled during construction mostly with the ground water that was pumped out from under it. The PB added "flocking" twice to clear it up. The water is beautifully clear now.
I only have the test strips given to me by the PB but here are the result:
Free Clorine: 3
Total Clorine: 3
Total Hardness: 250 - PB JUST brought this up from 100.
Pool is 16x44 IG Fiberglass w/1 1/2 HP Hayward pump and DE filter. There is a Heatwave IceBreaker heat pump and something called Heatsavr which is like a magical invisible solar blanket.
