It didn't?

I never rinsed that brine. There were plenty of organics. They were fixed
quickly, but they were still there. The 75 gallon did not have a protein
skimmer. Any excess organics were dealt by the system.

I'm not sure I'm down with this. If I put the water into a white bucket,
take it outside and look at it in sunlight, it's still yellow brown. Or
under the flouresents in the laundry room, or if I poured it into one of my
bluish daylight other flourescent tanks. I don't think the physical
spectrum of the light has anything to do with it (especially when the
perceived spectrum is white light). I think it has everything to do with
the fact that I put some Malaysian hardwood in some water and it has organic
properties that's going to leach, bleach, etc for a while. Or as Jim said,
for a long while :)

I could do this, but it costs money too. I'd rather waterchange every three
weeks instead.

I have not tested the phosphates. I doubt they would be detectable in the
system, but I don't know that we'll ever know because I'm not interested
enough to pay for a phosphate test kit :) If I had a problem, I might...
But I just don't see that happening.

What I can tell you is:

- There isn't a single splatter of cyano anywhere. Even where detritus
accumulates and those cool little worms in the upper lay of sand eat on it.
- Hydroids obscure the view on the glass far worse than algae.
- Plants that were previously heavily parasitized by filamentous algaes are
regaining their allelopathic abilities and chasing it off.
- New shoots and leaves have zero algal parasites.
- The system is being fed about 2 oz of food 5 times a week at this point.
Some food does make it overnight, and hasn't been a problem yet.
