how are you doing water changes exactlly? why do you think the salinity was raised? a water change should not effect salinity at all.
what test kits are you using and what did you test for?
well I usually put salted water in a bucket and the salinity of water is high for sure cuz I don't test it. I pull in a cup of water into the tank first then y filter would tell me the salinity, usually it will raise the salinity a little for sure then I just top up some tab water to lower it.
I don't have the test kit, I just bring it to the store and let them tell me, so I don't know the brand. They tested everything like salinity, ph kh
, calcium , phosphate, ammonia... Everything was good except ammonia had a little, but they told me it's right after my cardinal died.
Should I use distilled water instead of tab water? Should I add ph kh
buffer in the container before I purr them into tank? My urchin is still alive , but not really moving and spines are almost all gone. I don't think I'm going to keep him any longer...
