Stop dosing Calcium.

If Calcium is not getting taken up by hard corals, then you should not need to dose it.

You need to do a water change with freshly mixed saltwater to reduce the calcium level to normal levels.

Maintain calcium between 400 and 450. I try to keep mine at 425 but sometimes I slack and it gets as low as 350.

You don't have to wait 3 days between dosing alk and cal. Just a few hours. You just need enough time for the dosed part to mix into the water evenly.

I am just confuse with detritus never get clean in my tank! I think detritus got mix with precipitation so look its dirty.

might be Mg is low its will produce precipitation ??

Any detritus will get eaten and go away. The white will stay, unless pH drops low, which will dissolve the white.

Its seem like calcium reactor device doing that, need ph drop to collect ca.
