Covid hasn't been friendly to the timelines unfortunately.
On the bright side, my 2 new drum filters are finished and should be on a boat to Singapore soon. These fellows are originally intended for commercial aquaculture use like you would encounter in a highrise fish farm.
Each can handle 3x the capacity of my old drum filter.
This translates to a handling capacity of about 150m3 per hour at 20mgL suspended solids of >50um.
I guess I could breed soon hock or tilapia if food really becomes a problem due to covid.
