Compared to the mass quantities of other plants in there,  the ones that I
added were a very small percentage.   For one thing they were small plants,
(a Crypt and a small sword) in a 70 gal.

See I think this is where my problem was,   I cleaned it off well but I
don't think I got enough of the soft material off to slow the rotting
process down.   When I took it out of the tank,  it was quite soft which is
what triggered my memory of the algae and driftwood article I read in the
archives.   It was not bad at all when I put it in there but I believe it
was quite farther along in the decay process than what I thought

Even if it wasn't that bad of shape when you put it in there, it will
continue decaying which is what I think caused my problem.   I'll know when
I leave this tank alone for a while.  No matter what I have done to this
tank in any way shape or form,  this is the first time I have spent any
length of time without continuous algae growth.  The next piece of driftwood
I put in will have NO soft spots on it anywhere.    I like the sandblast

In the future,  I shall be much more careful when choosing driftwood,  the
reservoirs sound like a good idea,   We have one close by I may look around.

It looked white,   It took me a while to decide it was algae and not
something else like part of a Jobes Stick loose somewhere.   Besides that,
If I'm going to starve it,  I'm not going to do it with water changes.  NO3
in my tap is about 12 mg/l and Phosphate is around 2 mg/l (which BTW both
drop to 0 within hours after a water change).   Once I am convinced that
I've got the algae under control,  I am going to start experimenting with
adding higher amounts of nitrates and some phosphates.   Not making any
changes for a week or so just to make sure it is stable.

I'll by that,   Since setting this up,  I never have disturbed the substrate
much which is probably why I've never experienced it before.

Just keep up on maintenance and nutrients. If you do a big hack etc, use the
magnums to clean up afterwards along with a water change.

Thanks for your input Tom,  it is quite helpful.
