Re: [APD] Re: clay substrate & thread algae

["S. Hieber" <shieber at yahoo_com>]

If I looked down at the sand, I think I'd see a line ;-) 

I don't want to cross any lines; just report what I've
seen.

Daniel might not be using the politically correct term but
indeed I have seen long thin hairlike algae (call it what
you will) be among the first to grow and then disappear in
newly setup tanks. I thought I recalled Tom B. mentioning
something like this too, with bba being the next to appear
until the tank gets stable.  That's probably a butcher job
on whatever Tom said so don't blame him if it's a muck.
