I'd like to see what it tests at in the morning in relevance to Eric's chart showing diurnal variations in low and high alkalinity ponds.
The uniodized (NH3) and iodized ammonia (NH4), nitrites (N02) will normally be zip to negligible in ponds that are not heavily stocked. They're not really relevant in recreational ponds. Even nitrates (N03) are usually quickly reduced by algae and macrophytes.
Now that can be a whole different story in commercial ponds that are heavily stocked. I've seen ammonia kill fish in small over stocked ponds that are heavily fed.
I will test in the morning and post at about 9:00am central. Thanks for your interest I appreciate the lessons.................Budster
