Hi Jason:

Glad to hear the polymer treatment was successful - that's what I love to hear! Congratulations on the recent fish stocking also - now the fun begins.

I've witnessed some small fish [fatheads, small BG] suffocate due to polymer coating gills in windblown corners of ponds immediately following treatment [within 1-2 hours], but typically less than a dozen fish if any at all. The polymer sinks pretty quickly, within a few hours the window of risk is over as the polymer becomes part of your main basin/sidewall soil structure. If gill coating was responsible you'd see all the fish at once, not a few daily.

I suspect your BG morts are due to some stressed fish responding negatively to some other environmental factor - change in water chemistry, temps, low DO, or perhaps the fish were pretty stressed upon stocking. Thankfully you're dealing with just a few BG and they are cheap and easy to replace, but losing fish is still always a bummer - I've killed more fish than I can remember, unfortunately.
Feel free to contact me anytime I'll help however I can.

Congrats again on getting your leak issues under control and launching your fishery.

TJ
