Green water and CO2
 

I'm assuming stump remover is only sold on the west side of the pond.
That's what I use.

The solution lasts indefinitely, no refrigeration needed. Label the
bottle
as
poison
though! I haven't tried, but I suspect KNO3 would taste awful, and I
have
no
idea
what would happen if someone swallowed it -- it may well be toxic.
Left-over soda bottles with their labels still on are probably a bad
idea...

Depends who drinks it Michi... Salt Peter in low doses has a tendency to
affect male seuxal function... Kinda gets ya down if you know what I
mean..

I never really viewed algae as a serious problem or a problem at
all...If the water is turning green you might want to cut the feedings for
you fish down, add extra filtration, and do more water changes..All three
of
these suggestions have worked fine for mew in the past.. And well the
present.. The other thing you might think about is adding some plants, to
use up some of the excess waste as well..

Graham, your statement is generally true of tanks with fish, but because Shawn
has the green water, he is more likely in the low-nitrate category than in the
"most tanks" category you describe.

Green water is unliely to be solved by addition of KNO3.

Experience argues against this statement. Many cases of green water have been
solved by increasing NO3. The cure is not quick, however, and there must be a
substantial mass of healthy plants in the tank. If the green water has lasted
too long, the plants may not be able to recover fast enough to prevent another
greenwater explosion. The best route in this case is:

* 50% water change, dose Nitrate to 5-10 ppm (I believe Shawn is low)
* Three day blackout
* 50% water change, dose all ferts.


Best bet is to
use UV sterilization of the water column to kill the algae spores.

On this point we agree, if by "best" you mean the easiest and most foolproof.
But also the most costly.

I'm not sure that follows :-) I've seen green water in tanks with 10-50ppm
nitrate.
Probably Shawn should test the nitrate level before deciding on a course of
action.
