Any opinions on a saltwater pond being ran with biweekly 20% water changes, 1 lb of live rock per gallon and a appropriate sized refugium only? Could it work? Anything I can add (wanna skip the skimmer since something rated for the size of the pond is the cost of the actual pond) as far as debri go could a simple cuc of snails and urchins take care of it for the most part? all ideas and opinions are welcome as always you all help make the builds I do super smooth sailing with the combined knowledge. This will not be a reef tank and will be housing large fish.
