BB question

[thirty6]

Thanks, i knew i read it someplace.
If i go acrylic was thinking spraying it blue or black or just glue gsp to it and let it grow over it

 

[TRIGGERMAN]

maybe a gsp,xenia,kenya forest lol Could be interesting. I was thinking about something like that when I do a big system.

I saw someone with a mat of zoos.. I think I saw a tank with acans all along the bottom as well. I think either would be sweet if you could pull it off

i don't think you absolutely need anything under the rocks for the purpose of protecting the bottom glass from breakage. it's pretty darn strong. have you ever seen how the lfs workers move huge rocks in a holding tank? they are not as careful as you and i would be. a buddy at fishtown in ramsey showed me how strong the bottom glass is by intentionally dropping rocks to the bottom and then forcefully moved them around causing avalanches in an old beaten up stock 75 gal. live rock holding tank filled only about 2/3 of the way up.

i have a bb with some zoa garden on one side and most of the bottom surfaces is covered with coralline algae.

i do like albano's acrylic rods idea to prevent detritus accumulation though.

thanks Tom,

are the rods basically against bottom of glass and used to prop the rocks slightly off glass?

I drilled the rocks to install (& epoxy) 3-4 pieces of 3-4" acrylic rods into each one as 'legs', to have the rock sit firmly above the bottom

I used 3- 1.5" PVC pipe cut to 3/4" to keepy rocks off the glass. I also notched out 4 slices on the sides where it sits on the glass so water can flow under it.

Works good , no build up inside the PVC.

Here is a pic of my tank with the PVC under the rocks.

Cool. Thanks for pics guys

Either one of you keep wrasses? I lean toward them as some of my favorite fish, but not sure if they all require sand for proper setup.... If so that would be deciding factor

depends on the type of wrasse!

some wrasses burrow and some don't. even for the burrowing kind, some of them will learn to wedge themselves in tiny crevices instead of burrowing. i have a melanurus that at first sleeps in the "sandbox" i made for him but now he just wedges himself in a rock crevice and no longer sleeps in the sandbox.
