I run stictly power heads on my 10 gallon, and live rock
I am upgrading to a 29 gallon right now, of course that calls for more liverock and more powerhead power. prolly gonna just buy 2 new powerheads, much larger ones, and use the PHs from my 10 gallon on other tanks.
However, on the 29 gallon, I will be buyinga skimmer for it, and eventually, will star workin on a HOB
refugium....basically nothing mor than a modified HOB
