Re: Simone's H2S Problem


You may be over feeding your fish.  This is one case of the formation of

Anubias really do best when attached and growing on driftwood and/or rock

KNO3 and Pflanzengold 7 _ARE_ FERTILIZERS!!

Don't forget that it takes so little fertilizing to grow beautiful aquatic
plants and the fish are producing fertilizer all of the time.  The food
that you are feeding, along with the bacteria in the aquarium are breaking
down lots of the missed food and waste of the fish to make fertilizer.  You
can eliminate many problems by NOT fertilizing unless, as Karen has said
over and over "the plants will tell you" if you look.  Many people look,
but cannot see.  Really look and you will have less problems.
