Shrimp newbie. Cloudy water, dying shrimp
Hello all. I'm a newbie to inverts, I just bought my first red cherry shrimp a week or two ago for a nano tank planted with anubias. One shrimp disappeared, and I found another one dead a few days later. The remaining shrimp seem to be surviving, and a few of them have molted with no issues, but I've been fighting with cloudy water, and I'm not sure if it has anything to do with a problem causing the shrimp deaths. I've been doing frequent small water changes, but it just makes the cloudiness worse.
Here are my current tank params:
NO3 - 0
NO2 - 0
I haven't been able to find good information about what kind of GH and KH RCS need. Are these numbers okay? I've been slowly trying to neutralize my pH as well.
I haven't really been feeding them because the tank has a good amount of algae. I haven't tested for things like copper or other metals. I use Seachem Flourish liquid ferts sparingly, just a couple drops every week. I'm currently running two filters, an HOB and an in-tank submersible that came with the tank, to try to clear the water up and agitate the surface, which has an oily film on it. I don't have any bubblers or aerators, is it possible the oxygen is too low?
Thanks for reading!
