Is doing a water change with fresh SW
vs. mixed better? I realize that I
still need to supplement based on bio load and utilization from inhabitants. but it just seems a bit more natural to me, even though the water is coming from the California coast vs. where most of my tank inhabitants are from.
OK now for another one, is the water from the California coast, specifically (300ft deep off the Catalina coast), as nutrient rich as the native water where these critters are normally found? Seems to me that the water from a rich coral reef environment would have more of the natural elements that these critters are used to.
The reason for this question is that I have a 12 gal
reef now and all I've used is fresh SW
and it's very convenient. But, when I get the 100gal going wondering if it will be as effective. I don't mind paying the $0.35 a gallon every couple of weeks for 10-15 gal
