Those dopey fake rocks / barrels, etc.

well i bought rock from my local garden center, just rinsed them off and let them sun dry a few hours, in my tank they went (this was a new tank) checked the paramater before and after, all seemed fine so i went ahead and put driftwood and live plants, all seems to be fine, tank in healthy and fish are happy. i have some of the decorations in my other tank (small bridge and barrel) my royal pleco loves hiding in them both. he is still a little shy as he is fairly new.
