It's world aqurium day, so let's take a little time to celebrate our hobby and all that makes it great. 

Carrying on looking at how the chemistry of the water in our fish tanks impacts our fish. 

For some reason we like to dye our fish weird colours. but is this a bit of harmless improvement. Of course not.     

Let's start learning some water chemistry. I've tried not to make it too complex, but as ever I'd love to hear your feedback. 

With fish shops shutting right and left, the obvious question is why.
