No clue about reefs
my ammonia is up so i wanna knock away atleast half of it, i want to do a 50% water change. i have 1 problem half my corals are going to be exposed to air for a couple of seconds if i remove 50% is it safe? and for how long can i do it. i can remove about 20% and no corals will be exposed.... so can i go 50% without harming my corals considering they will be exposed to air for about 1 minute
