Very good info, MCA. I especially found the 'air pumps' attachment really helpful. I like the comparison chart of the different air pumps. I wonder how the Hi-blow brand of air pump compares to these models. Also, I assume that the 40L per 1200 gallons of pond water includes both the air that is used to aerate the pond and the air that is used to aerate the filtration system.

MCA: You can look up the specifications for HiBlow, Pondmaster (Danner), Hailea, or others and add them to your comparison. In the other thread there is a link to the Septic Solutions company that sell many brands. You will have to convert backpress in bars or psi into water depth in meters to make the comparison for air delivered at the same backpressure.


It would be nice if one of us could compile a list of the different brands and their advantages and disadvanges.

MCA: Other that capital cost (from which vendor on which day?), operational costs (stick to watts not dollars of electricity) and performance (liters at X meters).....what advantages or disadvantages should be noted?


We could also use comparison charts for the digital DO and ORP devices as well.

MCA: Don't know but of one ORP meter that can be calibrated by user that is afforable by hobbyist...PinPoint by American Marine. If there are others, that would be interesting to know.


This would really help those that are new to the hobby such as myself from wasting their time and effort in experimenting with different devices. Once again, very helpful thread. Thank you.


MCA: You are welcome.
