malaysian trumpet snails & laterite?
Taking the recent snail dialog underground <g>:
I've been considering setting a tank up with a lower layer
of gravel/sand with laterite mixed in, and an upper layer of
gravel/sand only, then tossing in some malaysian trumpet
snails to help keep the substrate clean and aerated. I'm
hoping that the snails will prevent it from turning black
in areas, while also stirring it up enough to allow some of
the nutrients in the laterite to escape into the water
column. (Poor man's heating cable?)
I'm interested in hearing from anyone who's already gone
down this road, and what sort of results they are seeing.
(Iron content in the H2O and/or algae growth any different
than similar tanks without the snails? Plant growth good?
Any long-term examples out there? Any problems with the
snails?) Also any recommendations as to size of
gravel/sand, amount of laterite to mix in, depth of the
Thanks in advance, Ken Cova
