I’ve had this running on my nightstand for a little over a year. It’s an Advanced Acrylics tank with the following parts:
IKEA led light modded with 3-up from Steve’s LEDs
Sicce Syncra 1.0 pump
Hydor 7.5w heater
Apex Jr.
My three year old feeds it flake food probably twice a week and it’s only had one 100% water change about 4 months ago. Top off with RO/DI. These little simple tanks I think are my favorites. All the stuff that grows on the rocks: pods, mini-brittle stars, tiny red tube worms, ball nems, vermitid snails, sponges, and bubble algae. It all seems to stay in balance somehow.
