[APD] RE: barley straw

 >From what I've read the pond folks have good success with barley straw.

So have folks that added enough plants to begin with.
Same thing with planted tanks and natural lakes. 
Gin clear water.

Rotifers do well also.

Sort of.
Still got plants, algae, critters, light and nutrients.
If you add one plant to a 55 gallon tank, is that planted?
Pond folks generally don't add nearly enough plants then complain about
Ponds with high plant density and growth don't have algae.
Same for planted tanks, the tanks with dense good plant growth don't have
Same for natural lakes that are shallow with lots of plants, no algae.
There are differwences with each water body, but there are still many of
the same things going on and very similar traits each one possesses.

If you have emergent growth, Riccia, Moss, anything that these can
entangle, you will cuss trying to remove them all.

Less light, then high CO2/nutrients is the best way to go and have good
plant growth and less algae.
This observation was confirmed again today on a large tank that a
mainteance company I work with. 

Folks will be much better off dealing with limiting light rather than
limiting nutrients. 
This allows for the most wiggle room.
But folks are too hopped up on high light means "I can grow red plants" or
"red plants *need* the high light" or such and "such and such plant needs
high light".

But then we don't need no straw, we got live, not dead rotting
plants(Barely Straw).
