Hi guys,
It seems as if LECA and similar products are not available in South Africa.
Thus my question is this:
The hardware stores and pet shops here sell what they call an aquarium filter medium which look like mini plastic match boxes; 2" x 3" x 1" with lots of grooves on each of the two flat sides. They say that these things promote the growth of good bacteria in your filter and because they are made from plastic they are extremely light weight when compared to gravel. (I can't speak for the wight of LECA as I don't know).
So, would these things work as a replacement for LECA and gravel?
I'm thinking of using this and wrapping them in an almost pillowcase type manner with a screen before adding the soil.
Should it be true that these things promote good bacteria growth and helps to filter that water, I can't for the life of me see that it can't work....your inputs would be much appreciated!
