OK After my headbanger post, and all of your helpful, (sometime truly prfound ha ha) input, I'm getting my 15" silver/red whatever he thinks he is a 150 in a few days. Now, the great transfer. I cannot use my well water, too hard and high ph. City water from her is 7.2/very hard. Can buy RO water, (hah! .40/gal), so i'm thinking 2 55 gallon drums full of water from west of the mountains that is perfect for him, plus the 55 in his tank, which had decided to do a little algae bloom. So, the 55 in his tank should be cleared up, I want to use new rocks, figured I'd transfer over used filters full of good scummy bacteria in hopes of preventing an algae population explosion. INPUT PLEASE, what's the best way to set this thing up with my water problems??
