I’ll check tomorrow and Monday.No let’s leave it, this system wasn’t built up strongly like the rest, so the test needs to be low level nothing like bottle bac stress.
That your surface area is over done like normal (rocks and sand) and the setup spans out the thin veneer of bacteria right in the line of flow, it will carry fish life and fish feed and waste in the tank to some degree.
testing that without fish, non digitally, can be tricky.
no matter how far we dig, there’s no info on unassisted marine cycles so this is neat to see. That test looks nice for sure.
lets see if in 48 hours it can move or not. We aren’t out of the woods no matter what at that point, about half a million reef owners actively state api shows some green at all sample times.
its the over reporting of actual nitrification that seems to be at work, your specific color shown above is found in many running reefs on api it’s a very tricky ref sometimes. 48 hours is a good start.
At any time those kits showing light green in api posts can test ro water and get yellow, it’s the active nitrification that seems to be a recurring issue in reporting correctly. the blank runs are always yellow.
Unless a kit like Seachem or instrument like Seneye specifically states that it measures free ammonia, i.e., NH3, the kit measures total ammonia, NH3+NH4, and the result must be converted to NH3 by consulting a table.My fault it was a bad flag event thank you for checking though. He posted a reading I thought was after a dosing of ammonia and showed none. But his post-dose pic made the api respond exactly right, calibrated against known zero condition. Very precise so far
*do api kits require TAN conversion like Red Sea does or are they different types / total ammonia readers
