I love your tanks, I love the use of grape and feather caulerpa. I hope you don't mind a few questions. I would love to set up my 29gal with some greenery (caulerpa), but I have heard nothing but bad things about it going sexual and destroying a tank. Do you have any problems with that, do you have to prun it to keep it in check (how often), and do you leave the lights on the same amount of time as with our corals? I told you I had a few questions. Also, do you have to add any additives to the tank other than water changes to keep it as beautiful as yours.
