I don’t know if this is a slight color change but I would like to confirm that ammonia is zero. This is a ten gallon tank with only a colony of neocaridina shrimp. My tank did not cycle properly at first and I had many deaths, but I haven’t had any deaths in a while and there are lots of little shrimp. It gave me hope so I tested my water. Nitrite and nitrate are 0. I think nitrates are 0 because of the amount of plants I have in the tank. The color is more bright and yellow than in the pic. Here’s the tank. Sorry for all the algae. Looks really messy on camera but I let the algae grow because the shrimp like to eat it.
