I never added sequestrant before. This year I bought a bigger pool, and it was taking so long to fill that the water started to turn brown before the water hit the pool outflows, so I got scared of staining and threw some sequestrant in. Big mistake! It added at least a week to the filtration...

Update: I was patient and a good boy, and I kept my levels right with the PoolMath app, using no chemicals other than liquid chlorine, soda ash, and muriatic acid (and some cya to get it to 30), and I watched as slowly that sequestrant wore off, finally allowing the polyfil bucket on the...

Great! Thank you! I will keep my levels right and wait. The pool has started getting darker, and the polyfil filter is starting to darken, so I figure that means the sequestrant is starting to wear off, and the iron is coming out of solution and finally getting filtered out. But taking a lot...

Oops! Wish I had read this before I went to the pool store. Back I go! I asked for Liquid Chlorine and they sold me this (see image): hope it is right! Sodium Hypochlorite To raise my CYA, is this the right stuff? https://www.homedepot.com/p/Chlorine-Stabilizer-5-lbs-Balancer-23505PTM/310588688

Yikes! Thank you! I just pulled that clorox stuff out and threw in my flipping frog - does that have copper? I will pick up liquid chlorine today. https://www.frogproducts.com/product/flippin-frog/ (Sounds like the pool industry is full of snakeoil!)

Thank you for clarifying! CYA reads as zero (black dot never disappeared). The kit is from last summer - I might want to buy a new one? Currently I am adding chlorine with clorox brand pool tabs (label says trichloro 95% (available chlorine 85%)...

Thanks. So you are recommending I shock the pool to get FC to 10 to break down the Metal Free Sequestrant? I assume by adding liquid chlorine or even (gasp) powdered pool shock? Issue seems to be Metal Free is polymeric not HEDP. Anyone know how to breakdown Metal Free polymeric Sequestrant...

I have high iron well water. It turns brown in the pool. When I set up my above ground vinyl pool each year, usually I filter out the iron with a polyfil bucket. Usually it works great. This year I bought a larger above ground pool (went from 1700 gal to 5000 gal) and bought a much larger...
