So your sayin just let it run its course before doin anymore water changes ?
The water is really cloudy buddy...
If I am in ur place I start using ro water and do a huge amount of water change...
And stop every thing exept for the skimmer...
And wait a while till ur tank is almost stable....
And only then start adding some machines plus what kind of salt are using and do keep it rest before adding it to the tank....
