Something I read once and have always done - it makes sense too. Boil the rocks after soaking in a bleach solution. Smell the rocks and if you detect bleach, boil again. You can smell bleach at such a low concentration, that I am sure you will be fine. If not sure, boil them once more *after* you can't smell the bleachI have plenty of rocks in my backyard but my house is new and with all the chemical and others things that were used on and around my house I decided I didn't want to risk that I had heard however boiling them would make them safe for aquarium use and I did boil some rocks but I didn't have the guts to put them in was to afraid of killing my poor fish.And with as expensive as rocks are at the pet store here(3 something a pound)I decided to forget it.But if there is some sure way to make the rocks safe please let me know

I uses them in a lot of my tanks like I mentioned before because they are a quick, safe, strong, cheap and easy way to make your fish more comfortable in this false habitat that we are creating for them. I just had to quote you because I was lmao when I read it. Bike tire...I think that could work.I find teracotta pots to be VERY ugly...unless your going for that '3rd world country ditch' look...why not throw an old bike wheel in there too.
Keep the plant pots for the garden or for breeding tanks in the back corner of the shed.
(Just my opinion...no offence meant if you like em)
