Rust stains on fibreglass pool

Metalic stains / using oxalic acid or a Granular stain remover. Several ways:
**1 Shut off filtration sys. /wait 5-10 minutes and broadcast powder directly over spots . wait one hr. and then start sys. with 100% suction coming from main drain. Wear gloves while handling product.
**2 Shut off filtration sys. / wait 5-10 minutes / if alot of metal stains along perimeter/edge of pool /fllor/wall , then at water line, against wall slowly sprinkle product so it will run down the wall . When it hits the floor a cloud may spread out. Wait 10-15 minutes because this cloud is still the product in a active stage, slowly moving down the slop towards the main drain. . Start sys. pulling from the main drain, cloud will dissapear in short time. Be sure to backwash in 12-24 hrs. max.
**3 Shut off filtration sys. / if only a hand full of metallic stains then add 1-2 oz. of oxalic into a cheese cloth/nurses stocking then wrap up and use rubber band or plastic ties. drop into water and position over metalic stain, holding it down for 2-3 minutes with net or wall brush since it may want to float .

There are other pouch type products also made for metal stains which are bascically a dry acid in a bag.
Remember, always wear gloves when handling problem solving products!

I would not fill your pools with acid, this can create so many other problems not to mention the costs associated with the vast quanties of chemicals you will need to get it back, I would drain the pool and do and acid wash, you can scrub the pool in sections and get good results.
For the person who had spots show up for no reason, do you have grass around or close to the pool? lawn fertilizer will leave rust spots due to the nitrogen in it, or your heater may have a problem with the exchanger.

There is a great product from an australian company - Lo-chlor, www.lo-chlor.com , and is sold in the US
http://www.lo-chlor.com.au/remprev_citraclean.php

CitraClean, it is economical (around $12) and a 1kg pack will treat your size pool.

it is a granualr powder and can be added directly to the water

we sell a ton of this every year for the exact problem you have - either that or people using angle grinders on steelwork near the pool. In 90% of cases you can watch the marks lift in front of your eyes

I recommend a product called metal-out before attempting rust stain removal. Combined with a floc application this will remove any metal traces from the water when you vac to waste, preventing future staining. Interestingly I recently found it can assist the removal of existing stains too. I had tried oaxalic without any success on a rust stain, yet after I had applied the above mentioned process the oaxalic removed it easily. The repeat application of the acid may have been a factor also I guess, I will trial this again soon to find out.

Metal out and similar products are sequestreants, and work fine when there is a soluble level of metal in the water - they are generally phosphoric acid based, they are not so effective by themselfs at removing the actual stain from the surface in my experience

We used vinegar, mop, and the sun. Pool cleaned up beautiful. You can also use Cllorox tub cleaner without the bleach for darker stains to break it first.

Try this.

Remove the chorine from your pool. Let is rundown to 0. Then add 1 lb of vitamin C per 10000 gal. I got this idea from another site and it works.

Use ascorbic acid. Most pool supply places carry this in bulk powder form (a little expensive 29.00 for 2 lbs. but you don't need a lot) and it really works great and fast. Sprinkle in pool with pump running (use recirculate) and in no time all stains will be removed from pool including rust, dirt, discolor, etc. Pool will look like it is brand new. Follow instructions... This is a pool service secret. Doesn't cause any disbalance of chemicals.

I have a fiberglass pool and have well water that have high levels of metal mostly iron and copper. My pool had yellow stains all over the surface and steps. I used a chemical from my local pool store call Iron and copper stain removal made by Poollife which made the stains disappear right before my eyes. It was great stuff. Also in past have use Magic Jack products that work well on stains which ordered from pool products catalog "In The Swim" company.
Good Luck.
