since brackish aint 100% fresh or salt, but still has salt in it, I wondered if I should have a skimmer or not. Watcha guys think?
nolapete;1167864; said:The specific gravity of freshwater is only slightly higher than "water," so the "surface tension" needed to cause the gunk (amino acids, etc.) to cling to the bubbles. Even at that, you'd need some really dirty water to get what you'd get from the same skimmer on a marine tank.
