I caught 33 crawdads overnight Friday night. This tells me I still have a strong population, but the water clarity is still improving.
Today's readings (Aeration has been running 3am to 8am)...
Time - 8am in BOLD , 1pm in RED, 6:30pm in GREEN
Ambient Temps - 64 F, 75 F, 84 F
Secchi Disk Reading - 21", 23", 23"
Water temps - Top to Bottom 73 F, Bottom 72 F - Top 82 F, Bottom 72 F - Top 81
DO - 4.8 ppm from surface down to 3', 7.5 ppm @ surface, 5.5 ppm - 12" down, 4.9 ppm - 24" down, 4.6 ppm - 36" down, 10.5 ppm @ surface, 6.1 ppm - 12" down. 4.7 ppm - 24" down, 4.4 ppm - 36" down
TDS - 45 ppm, 49 ppm, 48 ppm
pH - 6.8 from surface down to 3', 6.8 @ surface, 6.6 - 12" down, 6.4 - 24" down, 6.3 - 36" down, 7.8 @ surface, 7.1 - 12" down, 6.8 - 24" down, 6.7 - 36" down
Ammonia - 0.0 ppm, 0.0, Slightly Over Zero
Nitrates - 0.0 ppm, 0.0 ppm, 0.0 ppm
Phosphates - 0.0 ppm, 0.0 ppm, 0.0 ppm
Feeding was decent tonight, few HSB showed themselves at the surface or otherwise, but the HBG fed well.
I don't think there are any strong "take aways" from today's results other than the clarity seems to be helping algae blooms in the upper foot or so of water which really boosts DO levels there. I will continue running the aeration system at the same time (3 to 8 am) for the near future, but may start moving it to run more towards morning daylight hours to assist with keeping warmer temps in the pond as the cooler season approaches.
