Default Black Alge?

Have you tried Home Depiot , Lowes, Canadian Tire etc?
They sell stump remover.

I live in the USA and none of these places carry it. I never heard of

Look for "stump remover". Read the label (or google the brand name).

You should be able to find one in a hardware store that contains
potassium nitrate. Most of them do.

KNOW (Potassium nitrate, saltpeter) used to be very very common and
on every drugstore shelf as it has human and animnal medicinal uses
but in a post 911 world this major component of gunpowder is now in
the "you may sign for it" category. Any drug store CAN get it for you
but it's stupid expensive.

But, it's still the only decent stump remover so try then route. It's
cheap in this form.

You may want to get some ferts locally if you refuse to pay a shipping
charge, gas and running around will cost a fair amount also.

I looked for them locally. All I found was Muriate of Potash and those
mentioned above.

Muriate of potash is Potassium chloride which is seldom used in terrestrial
gardening and when it is, carefully, and is never used in aquatic gardening.

It's essentially, salt.

Salt is Sodium chloride and Potasium chloride is essentially the exact
same thing with potassium replacing sodium. It's sometimes used as a salt
substitute for people on low sodium diets.

In an aquarium you'd be driving the potassium too high and the deleterious
effects of that are pretty well understood and the chloride ions will
do plants no good.

1lb or KNO3 and 1 lb of KH2PO4 and maybe some CMS+B(the trace element
dry mix which is enough to make several gallons of trace mix for 1
pound) might make that shiiping charge seem for cheap.

It would be $30 for all the stuff on the Gregwatson page but I didn't see
any micronutrients there. I would then have to get someone to figure out the
mixtures per tank according to gallonage and fish load etc. Since there is
no guarantee these products will work any better than the expensive Seachem
products, I hesitate to purchase them.

I understand the mindset of "oh god I've added all these chamicals and had
no or bad results why should I ad more". BDTD.

But, ask people what has worked. You'll find a distinct lack of Potassium
chloride and a common element in succesfull aquatic gardens is the use of
potassium nitrate. This is about 10-15 years old now in constant and daily
use and you'd be hard pressed to find it's use earlier than that.

For 25$ or so with the shipping, you can fertilize the tank for several
years and have much better growth, thus you can send and sell the
plants easy and make up that few $ in shipping charge.

But what makes you believe these products will work better than the Seachem

Experience. Lots of it. By many people over a large number of years. The seachem
products work fine when properly used. Adding potassium chloride instead of
potassium nitrate is probably going to screw everthing up though, although it's
not a mistake I've heard of anybody making so far, so thanks for the data point.

That's your own barrier you place on yourself there.
You have luxury items like pets, 18$ can be had by selling plants,
other things laying around if a fixed income is really the issue.

I'll see of there's a market here for aquarium plants. The chains will not
even take them for free.

Typical. Try selling to hobbyists.

If I want something, I go get it.

As do I. I got the other products I was told to purchase and they didn't
work, so why would I believe these other products will work?

Asked an answered.

But you certainly do not "need" an aquarium......nor do I...........
You can check locally, but the shipping barrier is of your own creation
and getting the ferts which are dirt cheap and last a long time will
provide the means to grow the plants much better, you just do not think
that is true is all and not worth your time/$.

See above. The other products that were recommended did almost nothing
after the initial "boost" to the plants. What makes you think these other
products will work?

Asked and answered.

Try and get the ferts of a commericial brand cheaper, you cannot do
it.They might cost less initially but after one round of dosing, there
goes the cost and you have to pay tax, extra for a pretty label and you
get 500X less ferts.
That's fine, but it's not because they are $$ on shipping.
18$ can be had many ways if the cost is an issue.
Ebay or Craig's list something.

If I *KNEW* they would work I would order them. First I have no added CO2

I don't use CO2 on purpose. I know it'll work I've seen the (spectacular)
results and know I can get MUCH better plant grown (especially crypts) if
I use it, but being a luddite at heart I want to see how good I can get

which will be the next thing someone suggests is needed when adding all
these GredWatson "foods" to the tanks.... right? How can the plants
utilize the extra food without added CO2? Apparently Excel does nothing but
slow the growth of algae - from what I have seen in my tanks.

Not a good indicator given their chemical composition. Do you think the
poeple that have near-universally reported that it does do a nasty number
on alage are lying? As far as I can tell one other guy said it didn't
work for him but everybody else noted the was death on algae.

I've never tried excel without KNO3.

See above. Since the Seachem products did nothing for the new plants (why
were they even recommended?), and only a little for the old ones, I hesitate

Carol - you bought the wrong chemical. Try the right ones that people
have had wondefull success with.

You've been asking for 4 months how to solve this problem and many
people have told you how and you've done something different and
it didn't work.

Try doing what people have found works. Try following the answers you've
been asking for instead of making stuff up.

Barring that, try prayer.
