Cheap on everything except the light (learned that twice, hard way). Otherwise pretty low maintenance, if you don't count the rasboras (kinda addicted to watching them, not proud).
Avery HarrisReef Tanks
Barely touch this one most weeks (checking dosing and topping off is about it, and even that feels like a lot some weeks). The royal grammas ignore me completely, cleaner shrimp come out whenever food hits the water, and the montipora and favia just sit there doing their coloring up thing under the kessil. Wavemaker keeps flow moving so I don't have to. Low effort, good results so far.
Avery HarrisPlanted Tanks (Aquascapes)
Upgraded from a little tank that never really worked out (bad shape, worse light, plants just melted). This one's got the twinstar and an inkbird keeping temp steady, so no more guessing. Chili rasboras dart around the christmas moss and the hygrophila pinnatifida finally took off after sulking for a while. Blue bolt shrimp and nerites handle cleanup duty. Amazon swords are filling out the back, anubias tucked on the driftwood.
