@ligayagardener glad you liked it. Do you mean you with you saw it when you started gardening or when you started on Steemit?

When I started designing my system

Oh man. What problems did you end up having?

Nothing serious. Lack of N, algae, turbidity. We managed to work it all out

By algae I assume you mean too much not a lack of, correct? Glad to hear it worked out overall.
