The end of the Yeast
Does anyone know what gases Yeast gives off when the colony dies? Mine just
stopped bubbling, so I took the lid off and had a sniff, and nearly fell
over! Pheeew! Alcohol fumes & (I guess) hydrogen sulphide(Rotten egg smell)?
plus some residual C02, enough to floor anyone. But...Does hydrogen sulphide
dissolve in water? will this poison the tank? or if that isn't what is
produced, will what ever IS produced affect the tank? sorry to fire off so
many questions, but my tank is looking Mighty Fine and I want it to stay that
PS the sodium bicarbonate did the trick, KH is now at about 4-5 degrees ( I
think it was maybe 1-2 before, I may have misread the kit which is indeed
from Esha), pH is at 7. Rams eating voraciously as are cories. Few too many
nitrates/nitrites though....water changes ahoy!
