Closed pool with Iron Stains + Pink Algae... Now What?

[mbar]

I don't think it is as bad as all of that!!! I don't know where the iron comes from, I have been trying to figure that out for 6 years. I do know that once I get the pool treated and balanced, I usually don't have any more problems. If you keep up with your chlorine, you never need to shock. That is what I try to do - keep up with the water. Fiberglass pools are actually very easy to keep - there aren't any rough surfaces to get algae in. The most important thing is to keep your ph around 7.4- 7.6 - not higher. I also run my pool with a cya under 50, so I don't need high chlorine levels. I use regular bleach, baking soda, and borax. The only other chemical I use is the metal free (and ascorbic acid if I have stain). If I ever do have to shock, I put a puck in the basket, and use regular bleach in the pool with the filter running all the time. The high clorine levels will drop out any metals that are in the water, so by keeping the filter running with a puck in the basket, the metals in the water will stain the filter instead of the surface of the pool. It seems that when the water stands (filter off), is when the stains grab onto the surface of the pool. I think a lot of pools have stains, but the white fiberglass is more suseptible and the stains seem to show out so much. Once you get used to your own pool, and your water (it is all different) you will be able to keep the pool so easily. This will be my 7th year with my pool, and it really is simple if kept up with. My family laugh at me, because I actually love "pool maintenance".

I'm not sure what pink algae is. Could it possibly cause pinkish stains from the waterline up to the pool deck. That is what I was greeted with when I took the winter cover off my pool.(30,000 gal vinyl lined IG)
If it is pink algae, why was there no slimey stuff , just stains? Scrubbing and an enzyme cleaner had no effect.
Please help if possible!!
