BigDave is right! Make that filter work. Also, you may consider adding DE to your filter via skimmer. (See sticky). We will all be joyous when PoolDoc returns in full! Also still wondering about cal-hypo dosage.

26K gal 20x40 rectangular IG vinyl pool; Apr 2014: New pump, liner, auto-cover, & water; Pentair Whisperflo 1HP pump; Pentair Trition sand filter; Cover/Star CS-500 auto cover; Taylor K-2006C; OTO
AM:
Have backed off to 1 tab per skimmer per day. Will vacuum to filter this morning and see if it will catch and hold the sediment. I really do appreciate your help
PM:
pH 8.0, Vacuumed to filter. Basically captured nothing, returns basically putting what I vacuumed back into pool. No change in pressure and returns remain strong. Getting pretty frustrated.

Re: Iron in water source
BigDave: I am thinking that there was not enough calcium on the filter media to catch the sediment. He is only using 1 tab cal-hypo and has been doing a lot of back-washing. What do you think?
BTW, here is a link to adding DE: http://www.poolforum.com/pf2/showthr...to-sand-filter

Re: Iron in water source
I'm concerned that the filter is not working properly. As FormerBromineUser suggests, you can add DE to a sand filter to get it to catch smaller particles. You can test the filter with some DE as described in this link: http://pool9.net/de-test/. please do as it sounds like your filter is not working correctly.
Re: Iron in water source
I will get the DE and try it. I've been concerned that the filter is not working correctly also. As I mentioned I had the sand replaced when I had to replace the liner. Was something done wrong or any idea what it could be? Right now have towels is both baskets. Catching lots of mineral. Rinsing and repeating. Probably just entertaining myself as it would probably take a month of Sundays. Was hoping the reduced flow would allow sand to begin to catch something. Flow still strong however. Please understand my frustration is with my pool, I appreciate all the time you, FormerBromideUser and PoolDoc have given this. I've had a pool 15+ years and never had to deal with a metal problem before. Wow!!!

Re: Iron in water source
2/3 cup DE increased pressure 1 - 2 psi
pH 7.2, FC 5
Metal in solution, water opaque green.
Still doing 1 cup polyquat every other day.
Guess it's time to begin the cal-hypo again?

Re: Iron in water source
Forgive me for asking, but, why 1 C polyquat every other day? FC of 5 for CYA 50 should be fine for algae control.
How did the pH get from 8.0 to 7.2? If you used MA, did you backwash first? How did backwash look?
CC 0.0?
Completely opaque or cloudy? Are orange particles gone?
Is DE still in filter?
