That rock looks nice. Just what I wanted. Now when it comes to stacking. I have Hurd about 3 ways people do it.
1. Just plain old stack.
2. Drilling holes and using PVC
pipe to make the structure in the shapes u want.
3. Building a structure and using zip ties to attatch rocks. I went to the Dallas aquarium the other day and saw a lot of there stuff set up like this. And gave me some very cool ideas for mine.
Not sure what the good and bad to each is. The stacking scares me on this size ad cost of tank. That if i mess it up and it all falls down then breaks something. The zip tie one as well with the zip ties maybe breaking over time.
Ty for the link. Will be saving it so when I start this build I can get good rock. Love the big holes all through it.
