It is cheaper but I myself are not very fluent in using such ferts. I am going to give it a try and see how it turns out.

There are a few discussion about EI method on the net and the ferts you can order online from sabakagro.com.my

Those are new growth. Which is a good thing
Here is a picture of hairgrass runner

it will usually starst with a single leaf poking out of the soil (for me at least )

I rinsed the ring when I first got them to clean off the dust.
If you are talking about filter maintenance, I clean my filter once a month by rinsing the medias with the old tank water. Some will clean it every 2 or 3 month but that depends on your fish load, decaying leaf in the tank, filter size and so forth.
