I managed to get water column temps over the weekend to share...

My pond is 10 foot deep in the middle with the deepest diffuser 2 foot off that bottom depth. The second deepest diffuser is about 6 foot below the surface and the shallow one is in 3 foot of water.

My system was operating from 9pm to 9am (nighttime only). This should allow for about 4 full turnovers a day.

Water temps were taken at 5pm. The water in 10 foot of water was 80 degrees F and remained at 80 up to the 2 foot depth. At 1 foot is was 86 and at the surface it was 89.

Even with the lowest diffuser 2 foot of the bottom, I have no thermocline. I think that the water being lifted by the diffusers is also dragging water from beneath the diffuser up with it. I still ponder on what can be done to eliminate that dragging of water so that a cooler area can be created if that is even possible in my small BOW. I am considering adding 18" to my deepest diffuser.

I have shortened my run times from 11pm to 8am as 80 degrees is a bit warm for my liking.

Fish on!,
