I'm not a chemist. Can someone tell me what KNO3 is and where I can buy it
? I've been battling green water algae for a couple weeks now with no
success. I'm 2-day past a 5-day black out. I wrapped my 55gal in a heavy
blanket and duct-taped it shut. 5 days later I took it off and had crystal
clear water ! I was so happy. However, it's not been almost 3 days since I
took off the blanket, and the green water is reappearing. I was just
looking up UV sterilizers online but then I saw this post below, and I'm
wondering if that might be a fix without having to buy UV equipment. I'd
like to solve this problem as inexpensively as I can !

Hey, I'm having the same problem with my 30 gal. After the blackout my
water was clear as a bell, but now its starting to fog up a bit again.
This time I'm just gonna let it run its course. My plants took a
severe beating because of the blackout, so I'm not about the do
another one. I'm not sure what the cause of green water is?? I think
someone said it may be an ammonia spike or biofilter tampering.
Whatever the case, waiting it out seems to be a common solution..

If it gets any worse you can go to the flocculant (water clarifier) as
a last resort. I know a lot of people are against adding the chemicals
but after looking at a green tank for 2 weeks it might be the only
answer.

Thanks Marvin,
I have read up on UV sterilizers and was
wondering if they would be a solution. I will check it out and see what
happens.

Before investing on an equipement. kepp Light and CO2 on, dose KNO3
1/4 tsp every other day.

Grants stump remover .... The BORG and LOWEs carry along with most other
hardware garden stores.. There are other brands of stump remover in some
areas. It is fertilizer, strong oxidizer, explosive in some conditions when
mixed with the wrong stuff.. so buy very small qualities or the FBI will
likely visit ;-)

it works ...

KNO3 is Potassium Nitrate. It's used primarily to add Nitrates if your tank
is short of Nitrate.

Most tanks are not short of nitrate. Tanks that are short of nitrate
normally have lots of light ( more than 2-3 watts per gallon of flourescent
light) and injected CO2 at around 15-30 ppm CO2, and lots of fertilizers.

Green water is unliely to be solved by addition of KNO3. Best bet is to
use UV sterilization of the water column to kill the algae spores.

Graham.

KNO3 is potassium nitrate. The common name is saltpeter. It's a white salt
(visually indistinguishable from ordinary salt). You can get it at hydroponics
stores. To keep your plants happy, you should aim for a nitrate level around
10ppm. Get a test kit to see what nitrate level you have currently though
before throwing in any more -- in large concentrations, depending on
fish species, somewhere around 50ppm, nitrate becomes toxic. (Some fish
are more robust than others and will tolerate 100ppm, but don't ask me
which -- my tank never gets above 15ppm :-)

If you weigh out 162 grams of KNO3 and dissolve that in 1 liter of water,
you get a stock solution such that 1 ml of the solution in 100 liters of water
will raise the NO3 level by 1ppm. So, if you have a 500 liter tank at 0ppm
KNO3 and you want to bring it up to 10ppm, you add 50ml.

Dosing isn't that critical -- if you accidentally add twice as much as
intended,
you still end up not killing anything, so measurements within 20% or so are
good enough.

You can work this into US gallons: 4ml (well 3.8, really, but that's close
enough)
of the stock solution into 100 gallons will raise the KNO3 level by 1ppm.
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...

Cheers,

Michi.

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..
