Pond Boss Forums AERATION Systems questions Aerate in the day or at night?

Shorty, IME, YP are pretty heat tolerant as long as DO is good.

I know a few ponds well south of your clime with YP, WE, and SMB where the water at depth pushes 85 in the heart of summer with no issues at all as far as mortality.

I have shipped several YP to all of Florida and parts of AZ that are stocked into unaerated ponds and those are reported as "doing well".

If low DO problems have occurred, I would suggest aerating 24/7 and possibly get a surface agitation backup if needed, whether it be a Kasco or even a boat motor....
