API master test kit and co-op strips. Pretty well stocked, 14 neon tetras, 12 rummynose, 6 emerald Cory cats, 7 kuhli loaches, 6 long fin black skirt tetras, 15ish guppies, some amanos, ramshorn and trumpet snails… but it’s well planted, intense light and co2 injected, so I dose everything but nitrates and the plants eat all the nitrates up immediately.
