My memory is that Barry's water is very different from yours. His is
very lightly buffered high by silicates and has very, very low GH, I
think. His big solution was to get the essential electrolytes the fish
need back up with some Seachem "Equilibrium."
Mine is similar to his (runoff from snow, mostly over granite) but I
have higher GH than he does, so it isn't so dramatic as his. Mine is
still weakly buffered high by silicates (9 or 10 or so before
atmospheric CO2 brings it down to 8 or the high 7s). Then it stays
fairly stable because my GH and KH are both up around 4 degrees and the
KH provides pretty good buffering. It is around 60 ppm as CaCO3, of
which a good 0.3+ ppm is iron. The plants love it! Overall tds runs
I do add "Equilibrium" to any of my hard-water-loving fish. I also add
some boric acid to the desert pupfishes, which usually helps them produce.
High GH (8 or10+ degrees) seems to make eggs of rainforest species have
trouble hatching. It acts about like adding too much dye and the chorion
seems to get too tough to be broken down by the hatch enzymes. I have
never seen sound documentation of this, but it is common mythology that
seems to hold sorta true. IDK what effect it has on the ovaries, because
my fish simply won't let me fool with them.

Missing the end of the Dallas/Rams game, because the wet, sticky snow
has covered my dish. Just wait a couple of days and it will get there.
