thanks Sk8r....I have pretty much come to the conclusion that this cant be a 1 tank system lol......there are just too many critters I like that are not compat with each other :/....side note on the refugium, I have a MONSTER cistren under one of the back rooms of the house...closed concrete deal that was built and used long ago to supply water to the house before public water was avalible. I use it currently to supply water to my koi ponds and freshwater tanks as it collects rain water off the roof though pipes to the cistren....if I remove those pipes so its completely closed off from outside water and change it to a saltwater setup would it be ok for a refugium/extra water to cycle though the tanks ??? this thing is prob 8feet wide and 12 or 14feet deep :0. I have 2 wells i could use as a water source for the ponds instead
