Suggest upping your phosphate. I learned my lesson on that one.

How can I do that? Over feeding?

Also can super low phosphate my Coral recede?

How can I do that? Over feeding?

bottomed out nutrients are going to lead to a whole lot of problems if you don't address it.
increasing feeding. ditch your gfo for a while, skim less aggressively.

You can also just add phosphate to the tank to increase it. I don't add phosphate but I have to add nitrate fairly regularly to my tank.

It's better to dose it IMO because it won't effect your nitrate level, whereas over feeding or underskimming will.
