Well I would test first for ammonia, Ph, nitrite and nitrate, if your quality is fine, then I would slowly add do water changes. Personally I use pre mixed saltwater with a salinity of 1.024 from my LFS
, that comes from a company that is specialized in the field. But u could use RO
water pre-mixed in a separate bucket to do water changes.
In my experiences buying a test kit for saltwater is worth the 35 dollars u spend. But could be hard to read yourself, accurately. Today even I went to my LFS
and got my water tested and found out that my water quality was perfect, i thought my test kit was inaccurate, but its difficult to read sometimes. when in doubt ask someone, and if your not sure, ask someone else. And don't worry about asking to many questions at your LFS
that's their job, they may seem annoyed at times but f-um, do what's best for u.
So if your unsure about anything in the future, I cannot stress this enough, post a thread and ask questions. Honestly this fourm has helped me sooooooo much, I still listen to my LFS
, but always trust your own opinion, but don't be afraid to ask, because at the end of the day people can be wrong, and everybody's situation and tank is different!
