Lupin - thanks - on both threads.
Not to steal James thread here - but I've serious concerns about this well, because a large percentage of my outdoor container plants that are watered heavily from this well are also not thriving - no matter how well tended and fed - they start yellowing and weakening. There has been a huge population explosion here in the past several years, and I wonder about the water table - and I wonder too about the former quarry that they converted to a subdivision. Many factors - so I'm well leery.
Hope you can sort this out, James! Wish I knew more for your sake, but it is trial and error sometimes. For the sake of comparison though, you could set up a small nano (my favorite type tanks) and see if you have any trouble maintaining it with only bottled water. If you don't have trouble with that - it might shed light without investing a lot of money in bottled water for a larger tank. (I'm talking like a cheap 3 gallon Nano made out of a Lee's Critter Keeper)
