Re: Silicone vs. Silicone

Thomas Zaccone asked:

"Now I'm wondering about silicone.  The local pet shop sells silicone
about $5.00 for a small tube.
Home Depot et al. sells a large tube for much less, correspondingly. 
all types of silicone equally safe to use in tanks?"

The one you want is Dow Corning RTV Sealant 732. It comes in a large
canister for use with those glue guns that the construction industry
uses, and therefore is much more cost effective. It also does not
contain that nasty anti-fungal agent which can be very bad in aquariums.
That is about all that you need to watch out for.
