Can we make it work for reef tanks ?
Check this out gyus, I watched a movie about "Grander Water" (Austrian guy) this thing is not a filter and just using "energes".
This is in North Van and has 60days money back i wonder if we should look in to it. Copper will not do but there is stinless steel thing, the question however is how much flow needed for it to work?
