    Poly-fill Use

    Using poly-fill in the skimmers to remove iron. Should it float or sink? I repurposed poly out of a specialty pillow and it is packed into the basket but it floats the whole basket. I put tile to weigh it down. Is this normal?

    My Iron Stain Removal

    Howdy! Believe it or not I kept FC 3ish last year when the water temp was in the high 80's. My SWG is for 40k gallons and my pool is a liberal 18k. SWG @ 35-50 depending on sun hours and rain. I haven't seen algae, knock on plaster in almost a year. Full disclaimer: I retired about then and was...

    My Iron Stain Removal

    The pic that has the critter whited out is before AA. The other is several days after. I used SC-1000 sequestant a few days after which may have been too soon. This main drain is in the spa and is a return when not in spa mode. The red is returning. Since the red is going to the plastic first...

    VIEWER DISCRETION I apologize, I live in the country, no lanai, only pic I could find. Nevermind, I whited it out. You can easily see the red on the main drain. Studying the rest you can see the red in patterns. I made the patterns adding MA through a pvc pipe directly to the surface. A good...

    My Iron Stain Removal

    LOL. I am kind a done with the chemistry experiment. I don't mind testing with the K-1000 daily to ensure the FC and pH are present and constant. But doing the full testing, twice a day, well my wife wants her counter back. Before starting this process, I was keeping the FC 2-3ish and the pH...

    My Iron Stain Removal

    Tough crowd! All I seek is removing the staining which I accomplished. At this point is when/should I bring the FC and pH up to the recommended levels for a SWG pool. 1/2" of rain and mostly overcast all day. Todays readings, at lunch my K-1000 test indicated FC was still dropping so I added...

    My Iron Stain Removal

    So do I want/need to do that? It's not that want to see red, I just thought it was supposed too. An earlier poster suggested keeping the pH lower so the red doesn't stain again. How long will I leave the poly-fill in?

    Negative, will add acid after I test tonight. I won't have the poly fill until tomorrow. I may have added the SC-1000 too soon.

    Go figure, I took my chlorine jug up for a refill and figured I'd take a pool sample as well. PAP gave me a Smiley Face :) Congratulations You have perfect water! The only values that agreed with mine were the FC and pH. Their CH was 280 and TA was 80. I'll click over to the threads on how to...

    My Iron Stain Removal

    I am going to test again after lunch, to eliminate operator error. During my filter cleaning yesterday, I purposely only did one quick backwash so I wouldn't introduce fill water. I manually cleaned the filter. My filter is a modified sta-rite DE. Used to have the panels, now it has a cartridge...

    I did not use poly-fill. I was under the impression the filter would capture the sequestered iron. My staining is old. Pre auto fill days (added when the pool was re-surfaced) we used a hose into the skimmer. The back wash would come out orange. Now back wash is greyish, depending on how long I...

    We'll shoot, I bought a gallon of sc-1000 for metal control. Now I read that it will bring the FC down. I did expect difficulty bringing FC up after the ascorbic acid treatment, according to the articles, it's expected. The sc-1000 was also suggested in the article. I'll soldier through the gallon.
