Is your frag tank stand as lone or hooked up to your display

My reason is that I run a halide on the tank and have noticed the acros on bottom are richer in color but yet the one on top of rockwork are brighter. For example my red planet on top is pink. And one on bottom is dark red

I have a small bioload have a oversized skimmer I'm also in the process of changing from prodibio over to zeo.
I would keep they'll bottom and use small tiles for mounting of coral.

Roberto Denadai over on RC ran a tank using fake rock and siporax in his sump. http://reefcentral.com/forums/showth...iporax&page=18
so no live rock at all and his corals looked spectacular.

Thanks for the link. Nice tank he has

I would fill sump with rubble as I have a pail full in garage

Is your frag tank stand as lone or hooked up to your display

both my frag tanks have their own sumps and are stand alones

You can pull it off easy enough, but I would feel bad for the poor fish. They like a little rock work to hide in at night.

I'm sure that there would lots of cover with grown in Acros
I would like to try this but it won't be for some time

ive done rockless barebottom frag tanks without a problem, the trick is to run hydroton (hydroponic growing medium) in a media reactor as a "live rock replacement"

Yes I've been using hydroton for a couple years now

My tank is a bit reckless (untamed). I've been considering removing the rock to make more space for some coral colonies that are getting larger than the rocks they are on. Sump is full of rock, so I don't think I need the rock for filtration.

I'm adding 2 media reactors full of hydroton to my 2 sumps in the next week or so. The new dual RR cube tanks have less than 1 lb of LR per gallon, so the hydroton will help with the biological filtration.

I will be selling off most of my spare LR in my sump so then I will replace them with a hydroton reactor as well. This will free up a lot of space, even though I have a 90g wide sump, all that extra LR fills it up good.
