Nothing wrong with the 'look' of grape caulerpa - in fact I agree it's nice in appearance. It's the aggressively growing behavior which I'm wary of. The ability of it to choke out any rival type of macro algae as well as coral by the sheer speed and volume of its growth...Thus resulting in your need to prune them weekly.
I swear, if my macro tank was as labor intensive as your macro tank, I would have quit long ago lol. Weekly pruning of macros? Pshhh far too much work for me lol. Macro algae tanks are meant to be easier to handle and ARE easier if done the right way. Pruning in my tank is more like once every 2 months or so... at it's worst I had to do it once a month.
Just trying to make you see reason loooool. Then again, to each his or her own I suppose.
Cheers!
