Gomer; Thanks for the input, its all good, Planned on one of the 55's not to be planted for sure, the 40's are my choice for plants at this time, so far no CO2 is used and very little liquid ferts in what I have, plant growth is ok, all of my inhabitants seem to like it this way, so far since all of them are very different in needs and requirements. Still in the plan mode for livestock and flora, when I get to the point of removing the flooring for reinforcement we will finalize what number and size tanks will go into the wall. Again thanks for the advice, points taken.
