Oliver, I really appreciate all the info you are posting, free of charge. I have been searching the inter-net for 2 weeks trying to get info on aquaponics, and everywhere I go, people have their hand out.
I have learned more in the last hour from you than I have in the last 2 weeks. I have watched all those post on U-tube from folks that seem to be high on something, that profess to have the solution to a cheap DIY for an aquaponic system, but it is a wast of time. I am in the planning stage, but I am getting close. Thank you very much...John
