thanks dan. i really dig it. i wish i had some of your colonies so i guess that just about makes us even

.
i thought about a screen actually. if i were to have another tank built i'd probably have them cut a rabbit around the inside of the euro bracing to hold one. that might look pretty tight.
honestly though, the hood gives me more room to get in and work around the tank than hanging a rack. i couldn't come up with an aesthetic way to allow the rack to slide out of my way so i was kind of forced to work under it and there wasn't much room. because the tank's so wide, i can easily slide a hood to one side or the other and have all the room i need to get around.
it's also nice to eliminate the glare of a hanging rack.

the macro in the tank is still there, it's popped up in a couple more places around the display as well. i plan to keep it attractively pruned assuming none of the coming livestock does it for me. i did transplant some to the macro tank as well but i've had some real cyano problems in there (better than the display

) and it's not what i would call thriving.
i'm still considering it part of the new tank algae cycle but if it's still around at the new year i'll look at it a bit harder.
thanks guys for the comments and suggestions.
