So moral of the story is no don't use clay,lava rock or pea gravel in a marine tank.

My understanding is its basically inert. Its sintered at high temps so it has the honey comb type structure providing the surface are you would want and again from my understanding good quality ones don't generally breakdown rapidly. Once washed with ro water should be ok. If it could be used it would save so much cash because you can buy 50 litres of the stuff for around $30aud.So moral of the story is no don't use clay,lava rock or pea gravel in a marine tank.
More utter nonsense. There is no comparison to the open sea and an aquarium, that is exactly why ocean reefs are fine with black sand. Very few if any people use and are successful with black sand in a reef tank. Again , no one is using lava rock in a successful reef tank. Nor should anyone read this utter nonsense and think they might be able to get away with it.If you couldn't use lava rock for filtration no one would use the black sand in reef tanks and Hawaii would not have any reefs.
Hi guys I'm new here and new to reefing! This is my 1st post so be easy with me!! Just wondering if anyone has had success with the expanded clay aggregate commonly used I the hydroponic trade as a biological filter media? It seems to have a lot of the same qualities as something lije marine pure etc. But substantially more affordable. Anyone??
Ok boomer no one has ever used lava rock in a marine tank ever! We get itMore utter nonsense.
