220gl experiencing salinity drop

[tazzxx]

Hi i Set up my 220 in Oct and seem to lose .1 to .2 sg every 2 weeks. My awc water is testing ..2 higher than tank so my dt should be raising as I'm currently setup doing awc of 5 gls a day. Any thoughts?

Maybe the new water is lower? Also if your dosing a lot, that could be a difference.

Look for leaks how much top off are you using , also do you heat your new salt water? Temp effects salinity...
