where some heavily planted tanks have no algae because the higher level
out compete the algae for food and nutrients. Is there anyone on this list
that has absolutely no algae? Or is algae something inevitable? I also
remember that phosphates are the main contributors to algae... That's why

First, you're never going to be able to remove ALL phosphates from your tank.
And a good thing that is, too, because plants do require SOME phosphates for
growth. Reverse Osmosis water is not critical if you are blessed with soft,
low pH water (such as found flowing from most taps in, say, New England).
However, it does make life simpler if you happen to live in a hard-water area
(such as the Rocky Mountains), where pH adjustments are very difficult to
make due to high natural hardness and buffers in the water. I do believe a
certain amount of algae is inevitable, and not necessarily "bad." In nature,
algae is everywhere, and does contribute its part in water purification by
consuming excess nutrients and waste material in water. I have never kept a
tank that didn't contain at least some algae, somewhere in the tank. I don't
know of anyone who has been able to do that. The trick is in holding it down
to low levels so it doesn't become obtrusive, or mar the aesthetic beauty of
the tank. At least, that's my personal opinion.
