I'm considering doing a Brackish tank for a Green Spotted Puffer in a 55g.
Assuming I'd start with a baby puffer (and therefore would need a gravity of 1.006) can someone please tell me approximately how long purchase of 60lb marine salt should last me if I'm doing a 30% weekly water change?
Well for future reference, to get to 1.025 (full salt) you mix a quarter cup (about a sixth of a pound) to every gallon of water. So that's just over a pound per 2 gallons, so roughly 7 pounds per water change, so it should last 8-9 weeks. Feel free do double check or correct my math.
