Just a quick update... DO readings from a calibrated WM600 were compared with a professional calibrated YSI556 and the MW600 reading consistently show better DO reading than the YSI. Due to the professional calibration of the YSI, and it being a professional device I think it is safe to say the MW600 is not providing the correct readings.
The YSI shows I still need help with DO readings at 6:30 am this morning from 5.45-3.72 which it also shows a saturation level of 50-45% and the MW600 at the exact same areas and depths shows DO of 7.7-7.0.
Readings the evening before at 6pm on 7/25 from the YSI were 7.99-4.6 and the MW600 12.2-6.8
Luckily I found an equipment rental shop in Olathe, KS that was very helpful. If anyone else in the KC area wants to rent a meter for testing their DO fieldenvironmental.com can help.
The YSI556 provides a slew of info, much of which I still need to research but you other that might be interested I'll post the other specs.
Water temp was consistently 23.96c, PH was steady at 7.7 and ORP was 77.6-71.5.
If I add a 2 HP Kasco Surface Aerator what would you guys recommend for the running schedule. Would 24/7 during the summer months be the best bet? Then after summer slowly phase it out?
Thanks!
