How much is too much rock?

[TRENT]

I just bought 400lbs of rock for my 150 gallon tank. I'm not going to use it all but I hope to use most of it. Foot print is 48x24x31. Should I worrie about the bottom breaking out? It's Sitting on a very sturdy stand. It will be evenly dispersed. Here is a picture of my 125 long it has around 200lb of rock. planning on same setup just taller. Thanks

nad you should be ok.....put a eggcrate on the bottom then put rock on top. beside the weight of the rock will offset the water ....on my 75gallon i got 150 pound of rock on it

Weight wise you are fine.
Too thick of a rock bed can cause nitrate problems though.

Yes true, but if your refering to my tank nitrates are good. I do a 60% change every week and vacuum every other. Run a fx5, two ac110's and 4 powerheads to keep water moving. Thanks for replys.

Nice tank and filtration. The rockwork is nice, what do you keep?

Dude, you should adhere those tank killers together.They make this underwater putty, that people make their rock forms with.

Even if one falls and just only STARTS the fault/crack.

Overcautious judgment is key here.

If it helps, in a 220 gallon. 6x2 footprint. It's half inch glass (for the sides, I'm not sure the bottom is the same). In there is 420 pounds of large rock, and 230 ponds of sand. Also, two 15 pound peices of wood on slate. Plus the water. The glass bows down 1/4".

cichlids _killer tanks look good. What exactly does the eggcrate do? Do I still put gravel over it? I was hoping to make a RFUGF system. This way I won't have to vacuum very often if at all. Thanks everyone for the feedback. I can't wait to set up the tank (next week).
