I've found that getting 0 TDS in the East Bay with a 5 stage RODI is easy. East Bay Mud is already low TDS water.
I've been using a 5-stage system that removes chloramines (you need to do this) from Buckeye Hydro for over 10 years. www.buckeyehydro.com. All the RODI systems look pretty...
I don't have room for my Biocube 14 anymore. Free to first BAR member that can pick up in Castro Valley.
It's retrofitted with LEDs (ecoxotic), has a In-Tank refugium, and the back is drilled for a sump (which can be easily plugged).
