Just got my system ready for the next stage. Going to start building the surrounding greenhouse so that I can keep the dang deer out of my garden. That is what happened to my raised beds last year. Thought this time an enclosed one will work better. Getting to know a fella that has catfish in his pond that wants to thin out the litter. Thought it might be a good chance to add a few to my tank. So far I have gold fish as a start up and now ready for some eatable type.
