The fediverse needs a place for aquarists! Saltwater, freshwater, breeders, fishless aquascapes, ponds, puddles, and bathtubs. If it's full of water and you're proud of it, we'd love to see it.

That's a CO2 checker. I have an injection system set up and it helps me set the CO2 regulator based on the color of the checker fluid.
Cool! Thank you for sharing~
