I've been meaning to post this thread for a while (ever since I first changed Dorian's water that is).
Just a warning, make sure that when you buy gravel you sift through it a bit (perhaps even wash it) before you put it in your fish's tank (that is if you don't already do it). I bought some nice gravel from the local aquarium store and I didn't realise this until I did the first water change, but it had all these rusty pieces of metal wire in it!!
And this was gravel bought from a pet store.
That could've ended reallt badly.
Just a warning... you all probably already check the gravel and stuff anyway... but yeah. Maybe some of the newer fish owners like me would benifet.
