The fact that my fish were swimming around in a very normal pattern is the only thing that kept me from completely wigging out. They looked more curious about my concern. Normal swimming, a little chasing and some curiousity... Normal. The plants on the other hand... Well, I hope my new bulbs and fertilizer get here today. My package got sent back for "inspection" whatever that means. Thanks once again for the calm advice Byron.
Hold on. Nothing is wrong. Relax. Thanks for the validation, I needed it.
As for the ammonia, Prime detoxifies ammonia by changing it to ammonium which is basically harmless. Test kits including the API read ammonia and ammonium together as "ammonia". So the "ammonia" is probably ammonium. Which is why the fish are not showing stress. Bacteria and plants use ammonium/ammonia, so no issue there. I remembered you saying that but had a moment of panic when ALL of the numbers were so high. The colors in the little test tubes were lovely but I was in shock with how high everything was.
Nitrite. This cannot be at 5 or all the fish would be dead. Inga, I know you are deeply concerned about providing the very best for your fish, and there is absolutely nothing wrong with that. But I would not fuss over testing after a water change; test the water before the water change (esp for pH and nitrates), that will give you an idea of what is going on; and keep a chart with the date, time of day (this is important for pH and nitrates) and the numbers, so you can identify changes. The water change plus the conditioner will obviously affect the water chemistry. If you want to check these things again, do so the next day. Unless you see trouble of course. Yeah, I just wanted to check if it was coming down after the fresh clean water and a big dose of Prime. It didn't so, to me, that is validation that it is alright as well. I tested my source water and got a big 0 for Nitrite and Ammonia. One never knows when they add something to the water and our own water becomes more toxic to the fish. Apparently, this is not the case now though.
