How important is trace toxicity from glue securing airline barbs in the
caps of DIY yeast bottles?
I had several combined factors that may have killed 4 of my bigger fish,
such as pH and heater/room temp overheating, but also using a different
glue on the bottle caps for the new yeast batch.
I'd been using silicon before. The odd thing is, puttin the new caps on
a different tank, fish are fine.
I let the Outdoor Goop for 5 days, but it still had a very faint
plasticky odor. In a previous experiment with it on the same tank, I'd
let it outgas for more than 2 weeks, to no obvious ill effects. My
sister commented that Outdoor Goop is really toxic, she thought there
were warnings to parents about not letting children get hold of it at
any time. It isn't the same as the regular indoor Goop.
Goop was recommended on one of the other aquarium CO2 lists, but without
specifying which type of Goop. It does hold the stem and cap together
really well. Normally I'd prefer the silicon, but over several months I
found silicon is not adhering to the plastic of the bottle caps well
enough to hold up when I'm banging bottles about underneath the tank (as
carefully as possible, but still!).
Should I try gluing the next batch of bottle caps wiht it and let it air
longer, or give up and go back to silicon? Silicon isn't nearly as
secure or solidly attached to the plastic.
I was also wondering if I could get away with gluing the silicon first,
then layering Outdoor Goop over it only on the outside, or if I should
go buy the regular Goop (not outdoor), or if I should do the silicon
then layering with the regular Goop.
