Large white spots

Thanks for the advice guys, been doing water changes for the last few days and another one tomorrow. I think the spots are clearing up but now I see some small white ones *sigh*.

What percentage of water do you change?
Do you equalize the water parameters before you adding it to main system?
I suggest you equalize temp, salinity and ph and then add the new water via the sump.
