Hobbies

Some of my hobbies are simply my teaching or research applied at home, for fun.

Home aquaponic project: During my PhD I wanted a display tank at home that might also ustilise the rich waster products created by the fish (usable Nitrogen). I created a system which incorporated a fairly large (2m long) Malawi ‘Mbuna’ (rock dwelling) cichlids. In addition I added two sumps: the first to remove physical waster and the second to house a small hydroponic bed.

555 home project for keeping pretty fish and growing salad stuff from their 'waste'
Simple schematic of the plan , decided form the beginning to use DWC rather eb and flow etc for convenience
