If you put in a box filter to remove the dark color, arn't you just
removing the tannins that you worked so hard to get?

The tannins take on cations like CA and Mg in order to allow the release of
the H+ ions that increase acidity.  So when the carbon filter takes the
tannins out, it takes out the other stuff, not the H+ ions.

Does it make any sense using a protein skimmer to clear the water from
dissolved organics ?  They are fairly easy to build and, although it is
more complicated to adjust the flowrate of water and air for optimum
performance, even below optimum levels they are very efficient in clearing
water in tanks that get lots of frozen food.  Is anyone using skimmers in
breeding tanks for this purpose ?
