Hello fellow Rusty-Well Sufferer!
@Nate4429 I am here to help you in any way I can!
My pool went from brown (almost black) to bermuda blue in about 3 days with the use of a poly-fill bucket! I use my well as my fill source too - which after about 30 mins of well water, my blue beauty turns to a greenish gross mess.
Here's the ingredients for a successful Poly Bucket:
5 Gallon Bucket with the SCREW ON LID FIXTURE (you don't want to be neck deep chasing poly fill in a rust-filled pool at 10 PM... ask me how I know..)
Enough Cheap Pillow from walmart to have a SOLID pillow fight with an army from Game of Thrones (you'll want 6ish at minimum - you have to trade out the fill periodically)
Get yourself an adapter that fits from the Return Tube of your Pool - and drill a hole in the bottom of your bucket to fit that adapter (never hurts to have rubber gaskets, plumbers putty or whatever other water-proofing agent around)
Prepare your Bucket:
I gave mine the name Joe Dirt - yes the iconic David Spade movie... short of having a mullet, he was a pretty rad dude
Bottom of your bucket - drill the hold for the adapter
Lid of bucket - drill enough holes (more than you could think) to pace the water returning to the pool (I usually do about 30-50 holes on HALF the lid - I'll show you in a second...)
Fill your bucket with enough poly to "feel" full but don't smash it - you need the water to move through the poly and be filtered and not create a pressure spike on your filtration system
Rig your bucket:
If you're not dealing with algae your ladder is your new BFF
If you have algae forget the ladder and find another means
Hoist the bucket (full of poly, and holes drilled in the lid) - so that the holes are actually on the TOP of the bucket when you mount it
Strap her in - hence the ladder being your BFF... use your bungee cords and rope as a means of keeping Joey in place. I had to use a couple bricks to keep mine supported and from tipping backward
Disconnect your return from the pool, and connect it to the bottom of your bucket
**Be mindful when you take your bucket down - if you intend to backwash/rinse - you'll end up with rust right back in the pool. It's best to dismantle your bucket BEFORE backwash/rinse.
LET 'ER RIP, TATER CHIP! I leave Joe up long enough where my chems run balanced and I can VISIBLY see no more green in my pool. Sometimes it's 12 hours of run after a fill, sometimes it's 3 freaking days...
Give me a couple mins and I'll attach some pics to this thread so you can see my latest rig!
