I'm not sure why, but I have never been able to completely solve the algae
problem in my aquarium. I think its due to the 2.5ppm phosphate levels in my
tap water.

Boiling water is what I use to clean driftwood and anything else I can
remove from my tank for cleaning. I haven't risked using bleach or peroxide
on my plants, and have instead changed them to fast growing stemmed, and a
few fast growing leaf type plants, which outgrow the thin layer of algae
that starts to cover slower growing plants.

I did get the phosphate level down to 1ppm when I was cleaning the gravel
once a week , so if that, or excess nitrate is what is causing the problem
cleaning could help.

I need to eliminate the algae in my tank. I have been able to cut back
the lighting and to control the stuff on the glass. However, black
beard algae is growing on my gravel. I tried removing the affected
pieces but it comes back. BTW, I have a UV sterilizer. Can I remove
all the plants (if they died its ok) and treat the tank with an
algaecide? Then after everything dies, I could run my diatom filter
with charcoal to remove the algaecide residual. Then re-plant.

If you have a lot of plants, restore your lighting, fertilize well, and
start using CO2 or Flourish Excel. The plants should outgrow it. As
"feral boy" (???) said, siamese algae eaters will keep it under control.

Copper is the treatment of last resort for brush algae, and 5% bleach and
scrubbing will remove it from equipment. Normal algaecides don't do a
thing since it's a red alga.
