Uhh Problem?

[Geoff1991]

My mollys have been fine up until today when i installed a spray bar...

Been fine but in the last hour they have been very inactive. Black molly was just sitting on the bottom now im not sure where she is. Silver molly is just staying at the top not really moving, but she is alive.

I thought it could be the spray bar has lower the oxygen. So ive took it off and im just hoping for the best

Water stats

Ammonia 0
Nitrite 0
Nitrate 20
pH 7.6

Your water looks perfect. A spray bar should increase the oxygen, not lower it, because of the way it agitates the water surface. Perhaps the mollies were just psychologically stressed by all the sudden turbulence, and that's why they behaved strangely? Or perhaps the flow in there was so strong that it took most of their energy just to stay in the same place?

Anyway, as you've taken it off now hopefully they will go back to normal. You don't usually need a spray bar, provided that your filter outlet ripples the water surface - that will provide enough oxygen.

They still aren't right.

The just sit on the surface behind the filter not swimming

And hide at the bottom behind the plants when i put the light on.

Im starting to think its nitrite poisoning as i just did a fish-in cycle... (Not my fault)

Im off to do a 50% water change and see how it goes...

After a decent sized water change and a feed. All seems well. Whats going on?

And theyre back to hiding by the filter...

Any help?

Edit:

Nitrite or ammonia poisoning?
