salt in auto top off

[rusty18]

Does anyone add any salt to their auto top off or just use RODI/freshwater? Do you have any issues with changes in your salinity each month or does it stay pretty consistant?

No salt in topoff. It should be straight RODI since that is all that evaporates. If it is an auto topoff the the salinity doesn't swing at all.

Sometimes I add a little salt if I acclimated a fish and replaced that water with strait RO
