Benefits of fast growing cheato?

[bassman]

I have recently setup a fuge and have acquired some chaeto. However I am having a bugger of a time, yes a bugger of a time, trying to find a 5100K CFL to light my fuge.

I can find them on-line from the states but only if I want to end up paying $20-$30 for a single bulb after shipping etc. I have looked high and low at all the stores in my area and I can't find anything. First off none of the manufacturers seem to list the Kelvin rating on the package, which is very frustrating.

Anyways back the title of the thread.

What is the major benefit of having my cheato grow as fast as possible?

Of course I realize that a fast growing plant could indicate a healthy plant. But is it enough of a difference to really matter in a fuge setting?

If my chaeto grows but not at a super fast rate is it still doing it's job?

Are my PODs eating? Yup.
Is the chaeto absorbing nutrients? Yup.
Do I have to cut it back every week and sometimes have to throw it away because it's growing so fast? Nope.


Thoughts?



Thanks.
