You Must Have Rocks In Your Tank.
If your going to put rocks in your fish tank, there are a couple of ways to go about it.
Firstly, you could simply buy your rock requirements from any aquarium store with the other choice being to go out and find some on your lonesome.
It goes without saying, that a store bought rock will be ready to use immediately buth the downside is because they have been processed and prepared beforehand, they can cost you quite a bit of your hard earned cash.
If your a DIY'er and elect to gather your own aquarium rocks you will need to follow a few rules. Firstly, you cannot just add any old type of rock to your carefully managed aquarium. You will need to give consideration to a number of factors to safeguard your aquatic inhabitants and correct balance of your fish tank, becuase if you somehow managed to introduce the wrong rock, the result may well be catastrophic.

It's quite obvious that you could save some money by gathering your own rocks. but if you select the wrong type of rock, you could well be risking your aquariums health.
If you simply picked up some random rock in your backyard, there is a good chance that it may alter the water parameters of your tank. There are rocks that can change the pH and hardness level of the water and if you are attempting to maintain a specific, constant pH you may find that impossible to do with your new pet rock.
Something else to consider, is the growth for bacteria with some rocks harboring a host of bacteria which could easily thrive inside your aquarium.
A good rule of thumb is not to take rocks from dirty and polluted areas, sounds basic but it happens and you may also wish want to acquire solid rocks and not any brittle ones since they can easily fall apart inside the fish tank because of water erosion.
It may also occur to you, to source your new rocks from rivers and streams since these rocks are already used to water, problem solved, yes? Well actually it's not since rocks from rivers, streams and ponds can harbor bacteria and many microscopic organisms which are potentially harmful your aquarium.
While it appears to make sense, using those rocks which are found near bodies of water, it almost always ends up badly.
You should also ensure that the rocks you choose to put in your tank DO NOT contain any type of metal as many metals tend to rust when submerged under water and this is a very bad thing for the health of your fish.
Please avoid any and all metallic rocks in your aquarium at any all cost.Summary.
DO NOT JUST CHOOSE ANY RANDOM ROCK.
DO NOT USE ANY ROCKS FROM POLLUTED AREAS.
AVOID USING ROCKS THAT HAVE ANY METALLIC CONTENT.
DO NOT BE TEMPTED TO USE ROCKS FOUND NEAR BODIES OF WATER.There's Always A But!
But if you absolutely have to include that rock specimen gathered from one of the moon's crater's, then it may be possible to prepare and treat this rare jewel yourself, if you are prepared to invest considerable time (weeks maybe) and effort into doing so ... this is the scope for another post and it will be covered later.
If you do find some funky rocks in the wild don't forget to test them. Do the good old fizzzzzzzzzzz test.
Splash on some vinegar or if you don't have vinegar use the API master test kit Nitrate bottle 1 as it contains Hydrochloric acid (HCl)
If it didn't make it fizz its all good.
Fizz test huh, who knew. I normally get my rocks pre-fizzed. :o
