I've had my water parameters stable for quite some time. I added some acropora frags in September and a couple of them are very, very slow to color up (they arrived brown). One is a Hawkins, the other is a strawberry shortcake. Do some acros just take a really long time to achieve max color or is it unusual for an acro to take 2 months to color up. The Hawkins is only now beginning to show some green on the tips. The SSC is maybe 1/3 green.
