Re: Nitrate addition?
I am fond of potassium nitrate myself as potassium is rather very limited
in a planted tank. I add about 1/8 tsp weekly (sometimes biweekly) of
potassium nitrates for a nitrate level of 5ppm in my 20g long tank.

I do not know the contents of this buffer (perhaps greg would know? ;)
several buffers that I have seen do contain phosphates agents which do
lead to algae blooms ;) One suggestion is to mix your own buffer agents
so you will know exactly what is in your tank and what is going on than
putting an unknown element(s) into the tank and scratching your head in
wonder of an out of control tank ;) www.thekrib.com is a great place to
read about various different buffering agents and other tank info.
