Note my D.O. comments and Amano's additions of O2 at night and also the
pearling for 5-6 hours a day notion. Redox and/or DO may be a key component

 Additionally, it doesn't seem to have been

For me, the plants dominating and the algae not while having the same access
to nutrients is a curious one indeed. Algae control is good and all but the
bigger question looms here- not just another algae control method.

it might not matter - especially as

Here, Here! Back to science.

Maybe it's time for me to

You'll need to be able to grow specific types *well*. You can't just add
some hair algae to tank to see. It will die anyway many times from a  change
in conditions. Also, the straw helps prevent algae not get rid of already
established algae. So what are we testing here? A good result should be done
over the several week period also.
Comments on a good design for a test?
