Just catching back up - no notifications for some reason.
Definitely looking better👍🏻
I feel I should have mentioned this before as this has taken quite a while, but the more polyfill surface area the better.
This is why the bucket method is so helpful. You could also enlist a submersible pump in the fight as well since you really just need a way to run more water through more poly fill.
See👇

If you’ve got iron in your fill water, use Polyfill to remove it

EDIT: Found out this method only works if your iron is oxidized already, meaning it’s got a dull or bright green tint to the water, or a nasty brown tint. If you know you have iron in your fill water, but it isn’t oxidized yet, bring your pool to shock level and it’ll turn the telltale green...

Are you backwashing & noticing iron tinged waste water?
I just ordered some cellulose fiber to try this go round since I ran out of DE. Some folks have good results with it when it comes to catching more iron. Time will tell I suppose.

Thanks for the reply. I'm interested in the Cellulose Fiber. Can you use that with a sand filter in the same way you use DE? In terms of backwashing, I really haven't had to since my pressure has not increased by 20-25%. In fact, it's barely moved. I am planning on doing a deep clean of the sand filter because I have not in a long time in case I have channeling or something. But wondering with all of the iron removal if I should backwash anyways to just clear out any iron in there.

It is used in the same way. Here’s the instructions for the brand I bought but I suspect they are all the same
Its a little more expensive than de but I will use so little that is kind of a moot point.

A deep clean of your sand is probably a good idea. Should be done every couple seasons anyway & gives you a chance to inspect things. You should be prepared to replace any gaskets or orings & have some pool lube on hand before taking anything apart.
Do you have the s210s (mvp on the side)
or s210t (mpv on top) filter?

I don’t need to backwash often (maybe once a month or less) but when I do I always do it twice.
Backwash till sight glass water is clear then let it sit/refill a couple minutes and do it again. I almost always end up seeing more stuff come through.
Then rinse until sight glass is crystal clear & has no sand.
If we get alot of rain and I need to drain I will usually backwash then so I am not just wasting the water. I try to just take advantage of those free water instances to prevent having to replace any water with the hose since I am unsure about my iron content but I know I have copper in my fill water.
I usually add about 2 cups of de (mixed with a pitcher of water) after every backwash for a 1psi rise.

Thanks, what is the filtration difference between DE & Cellulose? After I deep clean the sand filter, I’ll try DE again but if I need something to get me to the finish line I’ll get some Cellulose Fiber. Thanks for the tip.

How effective is the cellulose fiber vs DE? Since I have the DE on hand, after I do a deep clean I’ll try a bit more to see if that helps get me to the finish line and then maybe order some CF if not.

I have an S210T, and replaced the piece with the gasket (forget what it’s called) when opening the pool (should have done the deep clean then but that was before I knew about that process).

Great tips on the 2x backwash and after raining makes a lot of sense.

Here’s what the backwash looked like this AM. Even though PSI had not increased much I decided to backwash to remove the iron and looks like the filter caught a lot of it.

Great 👍🏻 note that clean pressure and do the DE again.

The celluose fiber is supposed to filter down to 2 microns vs DE is between 3-6.
Not a major difference but
I figured it was worth a shot to try it since I ran out of DE & it comes in a resealable bag that takes up little space.

If I don't make any additional progress over the next week, I think I'll order some and give it a shot!

I have noticed that while the water color has certainly changed over the past few weeks, I have some rust staining on the walls and floor of the pool. Any ideas for how to remove those?

After slam is done & you’ve filtered out all the iron you can. Best to tackle the job when water temps are low to avoid gaining an algae problem.
