Ascorbic Acid Treatment - MBAR's suggestion

[mbar]

I am sorry that I don't have any experience with cartridge filters. I don't know that it would hurt a cartridge filter, because it is just taking the ph down for a day or two. I would check with the company that your filter is from. First I would check to see if it is a metal stain by trying the vitamin C, or you can put a little ph down in a sock and rub it on the stain, if the stain disappears, then it is from metals. If not it may be an organic stain, which then is lifted by chlorine. You also need to give a full set of numbers, because you also need your water balanced to see if any of the staining disappears without doing anything else. Let me know if you have any other questions.

Thank you mbar for your reply. I will do the vitamin c thing n check my numbers n post it and will let you know. Thanks.

Well, I bought vitamin c and tried putting it in a sock and pole and tried to rub it on the bottom of my pool, but that was too difficult as the stain was at the 9 foot deep end of my pool and the vitamin c kept on coming loose. I'm gonna try the ascorbic acid treatment and take out the filter cartridge to let the water circulate. Thanks for the help. I'll let you know how it goes. Thanks.

You also can put some ph down in a sock, or crush up the vitamin c and put it in a sock and tie it to a pole and rub it on the bottom (I know it sounds ridiculous hee hee, but it works) I hate to see you spend the money on ascorbic acid if it isn't a metals stain, however if you have been keeping the pool at high chlorine levels and the stains did not go away, or lighten, it probably is metal stain. Sorry it took me so long to respond, but I was away. Good luck and let us know how it is going.

Hello friends!!!

I'd like to thank Mbar and everybody else for helping me out with my stains. I did the ascorbic acid treatment and within an hour, at least half of the black/brown/orange stains on my plaster went away which I was very grateful for. Unfortunately, the rest of the black/brown/orange stains are still there, I'd say about 35%-40%. I don't have any numbers right now to put up, but I will do that when I get back home. I do still have very noticeable yellow stains throughout my pool and hoping some super chlorinating will do the trick. I'm not sure however, what to do with the rest of the black/brown/orange stains, I've been reading in this forum about some people using Muriatic Acid (I hope I'm spelling that correctly), does anybody have any sugesstions about the Muriatic Acid and getting rid of the rest of the stains black/brown/orange or yellow stains. I'd like to substitute the Muriatic Acid for the the Ascorbic Acid and do the same treatment as MBAR treatment. Does anybody have any ideas. Thank you for all your help and responses. Much appreciated.

I have places on my deck where splashed muriatic acid has eaten holes in the concrete, even when rinsed. I would NOT use muriatic for stain removal until marie or chem-geek take a look at this and give an opinion.....

Thanks Janet! I'll wait for them to see what they say or recommend.
