Stabilizing Rocks In Established Aquarium

[dmweise]

I have been having some trouble with my rocks moving around a bit as time progresses. I do not have anything that digs deeply in the sand bed and my base rocks are all touching the bottom of the tank.

The problem is that over time, the rock structures seem to become unstable, either due to erosion, critter movement, getting bumped, or me inevitably futzing with them.

What is the best way to stack rocks? Do they have to be 100% wobble free? Is there an acceptable level of wobble?

I kind of wish I was in San Antonio because I could just ask someone to drop by and tell me "Hey dude, you're tank is fine, stop worrying about it." but I do not have any reef buds that could do that here in Austin.

I think a small amount of wobble is fine as long as it only wobbles when you bump it - not just being blown around by powerheads.

(as an 'English as a Second Language' speaker I have to tell you that I love your word futzing! I'll have to remember it. It might just replace 'snazzy' as my favorite English word)

"Futzing" is a word that I enjoy quite a bit as well. I use it when I really want to drop the adjective form of the f-bomb but for the audience it is inappropriate.
