Reefing newb
Okay, so every week I change out 5 gallons of water (roughly 10%) of my 46 gallon aquarium. It's kept the aquarium clean and algae free (except for coralline that is). However, this past Wednesday I bought new corals (a lot of which were acros), and I placed them near the top of the aquarium so that they would get the best lighting. I went to do my water change today and realized that I can't take 5 gallons out without the acros coming out of the water. I could only get 3 gallons out before the acros started poking out of the water. Is it bad for corals to be exposed to air for the 5 minutes it takes me to change out the 5 gallons of water? Does this mean I'm stuck with switching my WC's to changing out 3 gallons at a time twice a week? Any ideas?
