Starting a new build. It is a 30 gallon hex. Will be using a aquaclear hob filter. Not sure of what size filter. Found a 150 watt HQI Solana light on eBay for cheap. Will have a deep sand bed for gobbies and maybe a jaw fish. Planning on doing a colom of rock in the center with shelf outcropings for mounting corals. Will most likely be LPS and some softies.
