On Saturday I added a spraybar, an inline reactor, and 4 card. tetras. I also moved some plants around.

After that the water has been cloudily. I did 2 50% water changes on Saturday, each time it looks clear for a little bit, then goes right back to being cloudily.

I also added a heater. I didn't have one hooked up as I live in Texas, and my temp is always around 73 or in my tank. However I added a heater to keep the temp a constant 78 degrees, even at night.

I don't know what's going on. I've lost all but one of my tetras. (7 total) and I'm pretty sure some amanio shrimp have died as well.

I don't know what to do. Should I do another water change today? It looks so bad with that cloudily water.

And please feel free to chime in - or if you think I need to move this post to another section of the fourm, so more people can chime it, please let me know.
Thanks
