So my my water has had a spike

 

[sikoko]

That's probably why do a water change and make sure all leftover food is taken out. What's your filtration like

 

[Pa777]

I have 2 large sponge filters and a Tidal 110 in a 90gl

 

[sikoko]

And how often are water changes

 

[Pa777]

I been doing 20% every other day

I would recommend larger water changes, 20% will not remove much.
