Was the added rock limestone ? If so, that will help craws, PKs and alkalinity.
I would add the ag lime to start but not all the salt. I would wait to be sure the salt was needed and only add in small amounts.
Agree on stocking plan + Sunil's comments. Long term my guess is you will need more forage base with YP , trout and SMB. FYI YP are known to stunt so you and the SMB will need to control that.
