Ok soooo, listened to all of your awesome tips, let the water run for a while and everything. Here is what I got.
Rain Water - 0
Tank Water - 0.25
Well Water - 1
What the heck? LOL! I tested 2x from the tap just incase I didn't let it run long enough and it was even darker the second time. I am just confused since the tank water seems to be lower....could it be because I have Purigen in there? Could I still try to keep some hardy snails at least like Ramshorns or MTS if I keep up with Purigen or Poly-Fiber or something?
