have you been able to get rid of the stains and keep them from reoccurring now?

Can someone help me with the following? :
Here are my numbers:
pH: 7.4 - 8.2
I have the same problems with my 3 year old fiberglass pool, and this year is extremely terrible. Muriatic acid takes the stains away, and putting sequesterant seems to help. But this year is different.
I have to put pH- every day. Once I put pH-, the level drops to 7.4. But the next day, it goes up to 8.0-8.2. It happens every day without a doubt, and it doesn't rain over night. The only thing is I put a little bit of chlorine in. (granules)
I would like to get my pH down so I can stop getting stains, but I just can't get my pH that low. I can't even get it to stay at 7.4.
I know that the municipal water has no iron in it, so my only guess is all the earth used in the landscaping around the pool gets into the water, and I think there's iron in the soil.
Does this make sense?
I hope someone can help.
Thanks a lot
