It certainly looks much more 'breathable now' . I believe you will eventually remove the top left piece though. Just my guess, It is a beautiful piece of rock, but the position is a little too high and may block off light to the bottom part. My apologies if i am overly fussy. . Just that i am essentially a SPS person and thus very particular about making sure i have light reaching all my corals.
Cannot be sure now, but lets have some corals in it after water is cycled and we shall see.
This hobby is fun with all the scaping and meddling isnt it? Heehee
