I found a pure commercial grade titanium basket for $44:

Do you think this would be sufficient for the cathode?

I also found a pretty good resource for industrial graphite. It's surprising
that it can be had for so cheap!

What I was thinking is to get the titanium basket and put the graphite in the
center of it, Apply electricity and wait. What do you think?

> Ya, probably 10 amps. You want more surface area and circulation than you do current. The problem you'll have is running out of copper atoms to remove from a given volume of solution around the electrodes.

10 AMPS?!!!?!????!!!?? Wow. Would a reduction in the amount of amps cause a significant performance penalty? My pool pump can recirculate the entire contents of my pool about 5 times a day, therefore I don't think that I would run out of copper atoms.

> Hmm, seems to me that couldn't possibly provide much copper, unless the whole thing disappeared...


It was a rather big bowl. I would say about 4 feet in diameter. Lot's of
surface area.


Would electrolysis work to also remove the iron in my pool using the same
materials (graphite and titanium)? If not, what should I use?


Here is the process I am considering taking:

1.) Drop pH to 6.8 -- any more and I risk damaging pool components (pump etc.)
2.) Add citric acid to bring iron into solution.
3.) Add EDTA to bind up the Iron and Copper
4.) Insert electroplating device into pool
5.) Test copper and iron levels regularly

Plausible? Or should I just live with the copper?


Thanks again,
