How can we make our hobby more "Green"?

Greenhouse. Solar. Geothermal closed loops for water as well as air temp control.

This last picture is hilarious, the girl in the back on the right is just so unimpressed by the boy in the front on the right.

You covered a lot of things. Not sure I agree with all of them (because I wouldn't ever be so compulsive) - but you get an A++ for ideas.

1. I have considered a small solar panel to help with electricity.
2. Minimize use of equipment , tests, i.e. purchase what you need (I think we overdo automation, testing, etc.
3. Use energy efficient equipment
4. Reef responsibly - such that there aren't fish deaths, coral needing replacement every month, etc.

Someone mentioned using salt-water to kill weeds. In some locations, its against the law to empty saltwater anywhere near a storm sewer (or where rain could rinse it into a storm sewer).

Thanks to the OP for an interesting discussion

Stop buying wild caught fish and coral as much as possible. Stop using filter floss (I think its polyester and I don't believe that actually degrades much), boohoo you have to rinse a filter pad or sock lol. Find alternatives to water changes.

Filter socks (at least the one's I have used) - contain plastic, also require replacement at times. Filter floss - on the other hand - can be rinsed and re-used - and you don't need that much. But - this made me think of another way to 'save' - stop washing filter socks in the washing machine. They just need to be rinsed.
