Esshup,
Thanks for the heads up, this really means a lot to me for the advise.
Actually, I was aware of the trout not being able to handle to much of the copper before applying. I thought real hard and worked through the "What If" scenario.
If I do nothing, the FA will consume the entire pond and we would no longer be able to feed nor fish. The temperature is rising and withing a couple of months, the trout would be at the temperature past suitable for life so I would lose the remaining trout.
With the FA covering most of the pond, the water is mostly clear underneath indicating, so I would assume, the FA consuming the nutrients that normally algae would be using for a bloom. With no algae bloom, less survival of the new spawn, less survival, maybe or possibly making an impact on forage for the bass. Remember, I have been having an algae bloom for 2-1/2 years straight & I am concerned that my forage to bass ratio may come to the equal point quicker than expected. I have just started harvesting the <7.75"CNBG & BG 2 months ago and have been catching 5" to 7" LMB, (3). My limited experience has me concerned that my LMB my have spawned late last year, Sept. Oct. time frame.
If I applied the cutrine, I could possibly knock down the FA bloom in short order and get my algae bloom going again, open water so we can fish, able to feed CNBG & BG post spawn and get their weight back up.
Down side to applying? I could lose my remaining 21 trout, if that many survived, which I would be losing within a couple of months anyway.
So, with this beginner thinking process, I narrowed down my best option matched to the overall good of this body of water according to what my desires are and push forward with the application of cutrine.
Now will be my time to figure out how can I once again introduce Rainbow trout this coming winter and avoid the nutrient overload.....
Sorry AB13 on taking over your thread....that was not my intension....
