I want to say it was around $6 for a 3oz tube. It wasn't the cheapest, but it did the job and was certainly cheaper than buying the same tube at a local pet store.
the small tubes are expensive and when i use it i usually let it cure for atleast 72 hours but i almost always let it setup for a week or more just to be safe
I have some GE II here at the house and after reading all the fine print (twice) I saw nothing that mentioned it as being safe for aquarium use. Does the GE I say something in regard to being aquarium safe and not GE II?
