Well one thing that's often overlooked: when you do your top offs, you only use RO or RODI water, no salt. You only use the saltwater you mix for a water change.aquanerd13 said:Perfect, thank you so much. Is there anything else I should know?
On the subject of top offs, take a marker and put a line where the water will no longer be at the right salinity due to evaporation. When the water hits that line, top it off
