so i found a nice 4-5" smooth rock from my buddies front yard. i wanna use it for my firemouth tank, trying to get them to breed. my question is what do i do to treat it? im guessin boil it but for how long?
Wash with vinegar and distilled water solution for the initial cleaning and scrubbing. When your rock is clean, use distilled water to really rinse it off. I strongly suggest, not just dumping it in your tank and praying at this point. Get a large container, fill it with distilled water and do a water test on it. Add your rock and let it sit for a few days, and again test the water. Compare your two results, paying close attention to your PH. You work hard to keep your water chemistry in order, lets not let your rock throw it off. If everything is roughly the same I would go ahead, and add to your tank. If It is not, you can "cure" your rock with water changes to your container with the rock (great more water changes) untill you get your rock to stabilize. Best of luck to you.
