lava rock to reduce nitrate?
I was reading articles about using lava rock as filter media. People claims that once the bateria is colonized inside the core of lava rock, it is very effective of removing nitrate from water. it sounds like a great addition to shrimp tank since we want as little nitrate as possible. Anyone has experience about this method? I am ready to go buy a bag of lava rock from home depot and put it in my shrimp rack's sump, but also want to hear more opinions from the shrimping fellow here :-D
