Is this enough or too much rock for a 65 gallon tank?

I got two 20 pounds for my 75 gallons.

What's all the difference between life rocks and Live Rock ?

Live rock is usually wet and has living bacteria etc already on it . Life rock is dead and would need to be cycled

Look great!!!

BUY THIS NOW! I was worried about breakage after reading reviews all four of my arches came well packed. These arches look absolutely beautiful cheaper than pet store! JUST BE SURE TO REQUEST AMAZON BOX OVER PRODUCT BOX to protect package contents... good luck

Awesome Broken Stones!!

Ya know, if these guys would invest in some bubble wrap, I’m sure their ratings would be really great! I got four BEAUTIFUL pieces, that turned into eight or nine beautiful pieces (after shipping). It turned into somewhat of a puzzle. I got super glue and everything is all good now, except you owe me a pair of work pants that I got super glue all over😂 No, seriously, if they don’t start using bubble wrap and protecting all of these stones, yours will be broke too. But they are beautiful when put back together.

No cracks!

Took a chance on ordering despite the reviews about the rocks breaking. Mine came well packaged and nothing cracked. Very nice shapes. I’m still messing with the rock placement in my tank. Im happy overall.
