Number 1 was actually up and running a few years ago - but, members come and go along with the motivation to continue this type of resource :((1) It would be good to start an equipment resource centre.
Having spare equipment at a location that financial members can access in times of failure/problems.
A handful of return pumps, circulation pumps and a few medium sized skimmers would be ideal. They could be loaned for a period of time and become available again to the community when the member has their tank up and going again.
(2) Community frag tank :)
