Re: Carnivorous plants

I have no experience with Hypertuffa either when it comes to bogs, etc.  I 
have leached concrete though before using the vinegar.  I sometimes use concrete 
blocks....aka cinder blocks in the ponds.  Before putting them in the pond, I 
soak them in a very strong vinegar solution (vinegar/water) for several 
hours.  Have never had a problem.   

Another suggestion, from personal experience.  I've done terra cotta and 
concrete pots for water/bog/lotus gardens.  I paint the inside surface...all that 
in contact with the water...with Dry-Lock.  It's a concrete sealant that one 
can purchase at Home Depot, etc.  I have it tinted to a dark color (comes in 
gray).  I have never had a problem with these either.  They make the pots 
waterproof and none of the concrete leaches out.  Totally fish safe.  One can use a 
non-toxic rubber like paint too, available at pond supply places, but it is 
much more expensive.  The Dry-lock works just as good at less than half the 
price.

As for Ceres' question about using vinegar water to rinse it to stop
the leaching...I have no personal experience here as I've not worked
with hypertuffa;
