Too many space requirements for a bigger tank. I think nano tank can be maintained with overkill filters. I have 2 tunze comlink filters, one skimmer, one coralife uv sterilizer and a ecotech wave maker, carbon, bio pellets, biospheres, pura complete, pura filter pad and the water is good. Maybe due to over feeding , my fault, there is a trace of ammonia around 0.15. Other than that, hardly need water change as nitrate is near zero. For some unexplained reasons, bubble corals do very well but the hammer and torch keep dying. If I can turn back time will go for a smaller tank like the prototype I saw at Golden Octopus which is a 1 ft tank but done so well.
