First off what are you using to test the Salinity of the water ? A refractometer or a floating hydrometer or a swing arm type gage meter, That would be my first question, Also I have never heard of salinity having any effects on Alkalinity or Ca other then if you do weekly water changes with fresh new saltwater then theses levels will be replenished to some degree .
Now at a True Salinity of 1.028 you really have nothing to worry about red sea for instance runs on average of 1.029 to 1.031 Only thing about really high salinity levels is lower oxygen as the denser saltwater makes it harder to hold dissolved oxygen.
Now having said all this to put your mind at ease for fear of harming your animals all you need to do is first make sure the 1.028 level is a true level and then if it is just pull out few gallons of saltwater and replace it with good R/O D.I Freshwater.. to lower it.. _________ Some of the world's greatest feats were accomplished by people not smart enough to know they were impossible (Doug Larson) |
