Too Much Live Rock?

[techen]

Hey salt peeps, I bought another 4kg of live rock from a member from a marine forum. I had 2kg to start with. That's a total of 6kg in a 25L nano, I removed some and I think I have around 4KG now in the tank and 2KG spare.

The question is does this look to much rock for the tank? My flow has a turnover of 55x.

Looks ok to me space-wise. The weight per volume guidline is just a jumping off point for building; nobody actually sticks to it to the letter, and one heavy rock in a small tank is enough to raise the weight per volume quite a lot. Only concern I would have is whether that big piece on top is really well-seated? Looks it in the first pic from the side, but then in the second pic it looks like a big thing propped up by a bunch of smaller things, which can be unstable unless they lock together really well.

It's stable, the only reason it's at the top as my Xenia has now stuck themself to it and I don't want to remove it and start over.
