You can crush up some vitamin C tablets put them in a sock and rub it on the stain - if they lighten then they are mineral stains. You can also try some dry acid (ph down) in a sock - it will not fade the stains as quickly as vitamin C which is ascorbic acid. If the stains lighten then you can...

Could be, but I did try some Sea Clear clarifier before that, so who knows? Water can sometimes be a mystery to me :wink:

I was having the same problem at the beginning of this summer. My free chlorine was losing about 1ppm overnight, but since I live in the woods I considered it ok. I kept my chlorine level at the high side of shock levels for my cya. I don't normally use algaecide, so I just kept the...

Try adding some metal out, while keeping the ph at 7.0 - it should lighten up the stains. If not, then wait till you have a problem with your water, and you have to rebalance anyway. One thing when dealing with a fiberglass pool is to make sure that your ph doesn't go above 7.4 - if you have...

My pool is 16 1/2 ,000 gal., and I used about 4 bottles of sequestering agent and about 5lbs of citric acid. After the stain treatment (three weeks ago) I have added about 4oz. of sequestering agent a week. I also used alagacide. My numbers are: FC - 4 CC- 0 PH- 7.2 Alk- 80 Cal- 200 CYA- 30...

Yes, the citric acid does take a little more, but it is so much cheaper. The stain doesn't disappear quite as quickly as with the ascorbic acid, but after being on recirculate for 2 hours you can tell if you need more. I also found it easier to rebalance my water after the citric acid this...

Are you sure it is a metal stain? If the ascorbic acid does not take the stain away, it may be organic. When you did the stain treatment did it all go away the first time, or was there some stian left? If it is metal, and a big area then I think that using the Magic Eraser would be too much...

Pink goop? It may be pink algae, which is a bacteria - make sure you take the chlorine up to shock (according to your cya) and keep it there checking on it 3x a day bringing it back to shock levels every time. The faster and harder you hit the algae, the faster the water will be ready to swim...

When you did the Jacks Magic stain kit, which one worked on the stain? If the ascorbic acid didn't work right away on the stain, then the stain is something other than iron - perhaps copper :cry: I know when I did the stain kit (many years ago) there were three different tests. I don't have...

Thanks Waterbear! I don't really read the forum too much, busy with grand babies :-D , but I will answer any questions about staining - just pm :) Hope you are having a great start to summer everyone! By the way I used citric acid this year instead of ascorbic cause it really got expensive...

I would try to remove the rust stains with a Mr. Clean magic eraser first. I usually don't bother with ascorbic acid with rust stains, because it messes with the chemistry of the water too much. If you only have rust stains, and not an all over pool stain, it is not worth doing the ascorbic...

You don't want to bring the chlorine up until all of the stain is gone - but if you want to swim, then you need to have the pool sanitized. However, the stain will sometimes lift with the sequestering agent if the ph is very low. The way stain is created is that when there are metals in the...

Sometimes the sequestering agent does get the pool a little cloudy. Just make sure you have enough chlorine in the water for the amount of cya you have. You don't want to start an algae bloom. As long as the chlorine is good, then you can let the kids swim. None of the ascorbic, sequestering...

Try keeping the ph at 7.0 to 7.2 and add more sequestering agent - try jack's magic, metal magic, sequasol, or some other metal "remover". Sometimes different sequestering agents work better at certain times. I don't know why, it just happens. Put the pump on recirculate overnight. See if the...
