Aquarium Advice FINatic
I have read conflicting articles about the use of lava rock in aquaria. They're so conflicting, that the extremes are:
1. Lava rock contains anaerobic patches which will build up toxic bacteria such as botulism, which will kill your fish;
2. Lava rock is porous and is therefore able to develop beneficial bacteria and can actually assist in the filtration of water within your tank, particularly for denitrifying: some people even use lava rock for pond filtration.
So, what do people think? Is this another Myth? I'm going to write in to PFK magazine about this to 'ask the experts' too, and will reply here with their response (if I get one!).
