HI,
I was tempted to try using well water , I have a shallow well, I also have a DSB in the sump and the main tank with a Flume, ( the flume was a under gravel filter wrapped with nylon screen to keep sandout and keepp sand out of the opening for the tubes I removed)My local well water has mod ca , some na,k cl and lots of IRON, almost 1,000 units per ml.
Now I have read that the bacteria in the flume and DSB, will incorporate alot of the iron fairly quickly as will any plants, I alos have a small reforguim in the sump ( more over kill)
Now my concern is this as this continues to accumalate the hydrogensulfiteoxide may reach a saturation point and kill somethin.
I may try a good water treatment that removes cholamine, chlorine and ammonia. it seems many chemicals as they remove cholimine the also make ammonia.
I plan to age the tap water after treatment and then add it in small quanities to refil the sump usally a gallon every day. It seem the well water help grow that nasty green algae after a few days.. My phos is zero I ve checked.
I know RO/DI is the way to go but isn't it a bit of over kill.

Hello Doug,

Your main problems with any ro system would be the iron and sulphur .
Either can and will foul a membrane . If I understand you correctly you
intend to treat both with chlorine . Our systems use two carbon block
filters so chlorine is no problem. You can go straight RO and skip the di .

If you go through alot of water each month, like more than a few hundered gallons a month, i would talk to hydrologix, they are out in chesapeake and make filtration for dialysis machines. Best water ive ever used and you pay per gallon used, price depends on water quality to start with. As cheap as .13 worst ive heard of was .45 per gallon.
