Tank Sealant

[Adam J. Kuhl]

I would like to clarify a previous posting to this newsgroup, both with
respect to tank sealants and to the customer support of Marine Biotech.
        1. Six out of our 68 large plastic tanks, with volumes of about 70
to 120 liters and 6 to 10 compartments, are leaking slowly at the seams.
The fishes are not in danger, but the water drips into storage space below
and the salt residue after evaporation is corrosive.  Marine Biotech's
technical support recommended repairing the seams with the adhesive used to
manufacture the tanks.  I was wondering, however, whether we could use
instead or additionally a sealant such as silicon that would form an
elastic seal at the seam.  We would like to apply that sealant to all of
our large tanks, as we clean them over time, as a preventive measure.  Has
anyone tried such an approach in their facility and could recommend a
particular brand and vendor for a sealant that is not toxic to the fish?
        2. The customer support of Marine Biotech, the manufacturer of our
tank system, has always been very responsive and helpful to us, in this and
in other instances.  They promptly sent us a free ample of their adhesive,
along with one of their new, more rugged 2-liter Z-mod tanks that are
molded in one piece.  I am not complaining about their products or
services; I am trying to find alternative solutions to my problem by
tapping into the communal experience of this newsgroup.
