I can sympathise with you Trod on the way you have to keep a close eye on things and correct immediately. What you think is a nice calm aquarium before you head of to bed may not be the same situation come morning. I'm patiently waiting for the day Seffies pupils say "Teachers not in today again" and we'll all know the reason why....poor souls.
A word on the photography front. Wait until the evening and dont use flash. If you photograph through the day you will see yourself in the tank reflection.
and the emerald crab may make a neusience of him/her self from time to time by nipping the corals. Keep an eye on the little begger.
Glad you liked the book, I couldn't believe you could get so much book for such a low price (Yes we know you got a bargain Trod). I would whole heartidly advise anyone new to reef keeping to make this one time purchase. Look at Seffie now, before she knew nothing now she's quoteing words like Dendronephthya at me.
And that's only since Saturday....Amazing. LOL
Anyway girls good luck with the rest of the tank aquascaping.
