These actually look like something called "bacteria house" made by using super heated ceramic. They are used in a filtration system for ponds called a "bakki shower." I think the stuff is made in Japan and probably why it is expensive.
care to explain that little more?? how to tell if it's fake or not??
the main reason i want to use it is to suspend my pothos from the bags of matrix in my sump so the pothos won't be submerged in water. if i use PVCs it's not beneficial to the sump i have so that's why i'm looking for this product.. my thought is why waste the space in the sump when you can use every bit of it...
that's really expensive and they look very different from what i have...thanks..
