we recently had a 2 day rain and my trout pond silted with clay banks are steep with fairly new growth. this happened in august and i read you guys talking about gypsum so i tried it. this cleared the pond nice and was beautiful. i also shut off aerator too settle pond on someones advice but guess what trout died and i dont know if it was gypsum or oxygen trouble that did it . someone told me gypsum probably plugged gills or too caustic. im in trouble now because it has been 1 week today (nov 9) and they cant see to eat i would compare it to coffee color i need advice on gypsum and trout pumping fresh water in wont touch the proublem HELP

I'm a little out of bounds, but will toss a few thoughts your way.
Check the pH and alkalinity of your pond. Then, add gypsum in small doses, so as not to dramatically change your pH and alkalinity.
Once you hit the "break point", the water will clear.
Your long term solution is to stop the source of suspended soils.
By the way, continue feeding the trout. They feed by conditioning and smell as much as by sight.
If you feed them, they will come.
