Re: Green Water

I've written a bit about green water in the past few months, but seeing
how I don't really like to search the archives unless I have to, I'll just
give a quick remedy.

I find that green water appears in tanks that are either K or N limited.
By having one of these the limiting nutrient, that means that P is always
present.  The way to eliminate green water is to shift the balance and
cause P to be limiting.  You can do this by adding N (easily obtainable as
KNO3), and adding K (available as K2SO4).

With the addition of both, green water should disappear in relatively
quick order.  I would guess under one week.  Mine went away in two days
once I realized that K was limiting.

Any questions, feel free to email me personally.
