This is sort of cross-posted for a quicker response:
What if an aquarist was willing to do religious water changes equalling or exceeding 10% of tank volume weekly (i.e. 10-gallon changes, 3 times weekly, for a 120-gallon reef)...
Would the tank fare well without any sort of filter or skimmer? is the water change and vigorous circulation via powerheads, coupled with the 1-1.5lbs LR
enough to keep the water conditions pristine?
If there is no skimmer on the tank, less nutrients are being removed, right? And at least 10% of the volume is turned over weekly, with fresh seawater. So would this eliminate the need for additional supplementation?
What if a skimmer WAS run on the system? Would the water changes so frequently be enough to keep the element levels up without any sort of additional supplementation?
This is just an idea I have been playing with...
