Mini tank crashes

[Wakestyle]

Hey guys I keep experiencing mini tank crashes every time I do a water change
And my hammers haven’t opened in about a week. Help?

Are you matching all your parameters when you change the water? your alk, calcium temp and salinity?

Run us through how you go about doing a water change.

Where is your water from?

What salt are you using?

How long after mixing are you adding it?

Are you matching Salinity, temperature, alk?

And finally what are your parameters?
