You can get a TDS meter on line for as little as $10. I bought one and use it to check distilled water before I start a batch and then ppm when done. I'm new to this, but from what I've read, maintaining a constant current is better than a constant voltage. I've used 24, 18 and 12 volt sources the only difference noted was the length of time for the process to complete. I'm not ready to invest in a constant current generator yet. Deposits and discoloration of the two anodes (Wires) is normal, just clean well after use. From what I see on the forum, the brown stuff is agglomeration. I get it too; it won't go thru the coffee filter. Hope this helps. Opa
