If you're worried about rock slipping around I mashed a few wads of epoxy between the glass and the rock-to-glass contact points on my 225 gallon. Kept the base rocks from budging (It was very difficult to pry off when I drained the tank!)

was actually thinking about this for my next tank.

are people still using this?

Years back, when the BB rage began, we had 3 BB tanks - a 180g, a 72g and 37g cube. Not once in the time I ran those tanks did a fallen rock break the glass. And there were plenty of opportunities for rock to fall because I loved to re-aquascape :biggrin:

When we began running our tanks BB, we missed the look of the sand. Well, we missed the look of what a lovely white sandbed should have looked like because our sandbeds after a couple of years looked grungy - which was the reason we went BB. Eventually coralline algae grows on the glass, so nothing is really lost in the esthetics department.

I've debated putting a skiff of sand in our nano. But everytime I look in the bottom of the water change bucket I see the amount of crud siphoned out. It's a no-brainer to stay BB.

You've gotta get some picks up of your new tank!

Hi Ken,

I've been meaning to take new photos, but think I'll wait until the LR I bought in early December cures. That way, I can re-aquascape (my favourite thing!) the new 25g combining the new and old rock :)

:mrgreen: very exciting! good luck(sorry all didnt mean to hijack!!)

Wow, quite surprised how many use eggcrate.

I myself use fine araganite, and then placed my rock on it... When creating my landscape I would work/wiggle the base/bottom rocks into the sand so the were basically at the glass bottom, and then the sand is all around the base.

Nice thing with this is that I can syphon my sand, of which I have been doing for about 6-8 months now, since I was having coral issues.

And I guess like others stated, I can go bare bottom if I wish. I won't, but I have that choice.

I guess if you are concerned about falling rock, breaking your bottom pane of your tank, then it would be a matter of making sure everything is secure.
