So, at this point we have two good media mixes recommented for scaling:
1. Three parts RINSED PERLITE to one part MILLED RAW SPHAGNUM MOSS
2. Two parts MILLED RAW SPHAGNUM MOSS and one part PLAY SAND or second choice, two parts MILLED SPHAGNUM PEAT MOSS and one part BUILDERS SAND.
If you read between the lines here, take note that the mix ingredients are virtually inert. The reason being that as the bublet grows, we want it to get all of its nutrition from the mother scale and consume it totally rather than have the little bublet take off on a life of its own allowing the mother scale to rott next to it.
