That's a heck of a front porch view- very nice, calming and inspiring! Can you tell me more about a de-gassing column, since I've never heard of that???
I had many tropical fish tanks, so I understand about NH2 and NH3 (ammonia) and biomedia for small fish tanks. What is a good low cost biomedia for a 1/3 acre pond? Why would I need to de-gas well water? This well water is heavy mineral water, lots of iron I know, but not sure what else?
Because it is pumped, I can lift it several more feet and then cascade into pots etc. What size pots would hanlde a 25-30 gpm flow?
Michael what you are doing may be just fine. Sounds like you have no low D.O. problems or excess nitrogen problems. Usually well water in our region so low in ammonia I wouldn't even worry about.
The columns are more to increase D.O. saturation as high as possible, and blow off the nitrogen gas and in some waters C02. However, excess nitrogen is really not something to worry about in your pond as there is plenty of room for it to disapate.
What If I send you my D.O. meter which is complete with temp probe accurate to 0.1 degrees. Just promise to send it back when you're done. Then you can let us know what you find out.
Here once again is my packed column which consists of 1 inch plastic media in five gallon buckets.
