My neighbors trout pond, very clear artesian fed water, is unable to even keep fatheads because the trout commit genocide on them instantly. You throw 5 gallons in and they are almost entirely gone, NOW. I have now added small mouth to my pond to use the minnows and hope that the smallies will reproduce.

Bill Cody, you think that using bluing and decreasing natural DO outweighs the mechanical production of DO I may have? I have an aerator and fountain running 24/7. I was trying to keep my water as cool as possible while hitting it with mechanical DO production as much as possible. I've been going for super DO saturation to get my trout through the last two summers.

I really don't know if what I've been doing is working because the last two summers have only seen my water get into the low 70's max, not super hot summers. The trout I have lost have all been 24" or better Goldens and one 20" rainbow. The goldens seem to be the most heat sensitive.

I just got a new pond, I made it twice because I aint so bright.
