No aquaponics setup yet but I have everything I need. Fish (2 crappies), 100 gal aquarium, plants. pond grade pump, hose, pond grade biological filter, inline UV filter.

I started getting coffee grounds from Starbucks (10-30 lbs a visit) to get a worm farm going. Earthworms for my fish. Two small aquariums are full of 50:50 potting mix and coffee grounds, growing lettuce and worms.

Later I learned that you can just dump the coffee grounds on a patch of untraveled ground. The worms will come.

The 100 gal setup is in my garage. Need to suspend the hood with its LED tube-like lamps, without the large pond grade filter getting in the way. I bought pond type equipment instead of the usual pet store aquarium equipment, because I want to scale up at some point. Might as well start out with equipment that can support a decent quantity of fish, with relatively low maintenance.

A huge part of low maintenance means - to me - not having to clean out any filters as an hourly or daily type of routine thing. Not having to buy high priced, low capacity filters, supplies, or cartridges.

I am not much of a biologist at this point. Somehow my two crappies made it over the winter. I have long since killed off (through incompetence, not neglect) the catfish in this video.

The 100 gal tank was not designed with a place to fit my large pond grade bio filter. The bio filter gets in the way of the aquarium cover/hood (not shown).

A frame will allow the bio filter and some plants to fit under the standard aquarium cover. The cover has two 4' long LED lamps. The LED lamps replaced two working fluorescent tubes. I upgraded them for energy efficiency. The LED lamps are relatively idiot proof because they don't require you to remove the ballast wiring always present in fluorescent lamp fixtures. Some similar LED replacement lamps require you to remove the ballast and rewire the lamps. Nice that I didn't have to bother with that.

One major difference from this pic/the video, and how things work now, is that then I had a standalone aquarium sized uv filter, with its own motor and particle filter. The cheap POS died after a few weeks of intensive maintenance, i.e. cleaning the particle filter every day under a garden hose. I'd pull the UV filter unit out of the aquarium, disassemble it, wash its internal filter, reassemble, reinstall the unit in the aquarium, and without fail come back a few hours later to see the filter plugged with gunk, utterly useless, its motor stalled.

Next time my town has an electronics recycling event, out it goes.

Now I have an inline 18 w pond grade UV filter, no moving parts, connected inline between my intake pump, and the large biological filter.

Low maintenance.

The 100 gal saltwater tank and cabinet were gifts from a friend. He was happy to let go and see his gear back in action.
