Re-potting a phal repeatedly using new media?

[flowerpower]

I re-potted my orchids last month using a garden centre generic "orchid compost"... The media looks very dense.. Almost like soil with a few (scarse) bits of bark! I have read horror stories about root-rot.

I can't stop thinking about my orchids' roots suffocating in this medium... I just want the best for my orchids!!!

I've ordered a new orchid media from a site recommended by RosieC (Medium grade fir bark).

Is it OK to re-pot AGAIN so soon? With a 2cm spike (sent out from an old spike). There is also something growing up from between the leaves which could be a root or a spike, it's about 2 cm tall as well.

What do you think?
