Were the BG the target species TJ?
Or just killing everything so you knew you had a clean slate to start from?
Will the lime Ph spike affect your aquatic vegetation problem?
I discovered I accidentally introduced 1 BH and 2 Female BG in one of my minnow stockings...becoming a recurring issue with me. Those BG were just mature enough to pull a limited spawn - I ended up only verifying 4 YOY BG, but you know next year it would have been out of control and my fishery would have been ruined.
Bottom line for me - it wasn't nearly as bad as I thought it would be [YOY BG], but all it takes is one female to ruin the entire fishery - so I had to do it.
I learned a lot from the experience I will post soon.
