I personally would like more cliffstone for my tank. How did you treat your stones before adding them? Just a soak and vinegar test or just soak?
I scrubbed them down with a hard-bristle brush then soaked them for a few hours in the tub. Rinsed them off and put them in. I've had them in there for about 2 weeks now and no issues so far (crossing fingers).
I avoided anything that looked like it contained "metals" or "sparkled." Eventually I'd like to find some nice big lava rocks or something like that, but haven't had luck finding them around here yet and couldn't pass up these "free' rocks.
