Tom,

You're my hero.

I've copied and pasted you post to my "stuff" folder. I got paid today
so I am gonna visit the LFS for SeaChem or something like it. I have
been slowly aquiring a list of aquarium chemicals. I'll try to add
KH2PO4 to the inventory.

Algae growth is about half what I started. I know I am getting
somewhere..... slowly.
