I'm in the same boat it appears. However my situation is a little more involved. I'm in the process of starting a new aeration system. Yesterday, saturday, was my 8 hour day for the system run time. Today should be a 16 hour day if doubling of the time is the recommended process. I lost two large catfish over night, one the day before, four the previous week, and 6 over the previous month. I figured that I needed to get the aeration system up and running quickly in order to stop the catfish kill rate. But am I going too fast? yesterday I ran the system from 2:30pm to 10:30 pm. I started today at 11 am. Should I cut back to 12 hours instead of 16 hours?

The pond is about 1/2 acre in size, with the deepest section at 8' to 9'. The pond is basically two triangles attached by a channel. The largest triangle has an island in the middle. So there are two stations in this pond section one at the deepest 6' section and one across the island in the next deepest 5' section. Then the second triangle with the deepest 8' to9' section has the last aeration station. This section also has a waterfall that comes in the farthest from the deepest aeration station. I have a Vertex HF 3+ XL2 with three stations in the system.

So should I stop running the system start up process? Or should I ramp up the system to full time. The pond has LMB and some type of catfish. There are also mosquito fish and a few large gold fish. I'm not finding any dead LMB or pond whale sized gold fish. What should I do?

Yesterday was a cooler day with temperatures around 70. Last night was cool also with the lows down to 43. It is 73 now and might make it to 80's. This coming week will have temperatures back into the upper 80's. I'm located in Northern Nevada just east of the Sierra's and Lake Tahoe. The water temperatures are in the low 60's.
