did you have one as a sample, i have an idea for a rectuangular one with tapere edges
 
Neil, I have been using these for a couple weeks now. Uncured they work just fine in my frag system. These work better for me than the Boston Aqua farm plugs becaus ethey fit in black eggcrate. Can you sell me 100 of them this week?
 
Just like to add that the plugs are great and cheap!!

I would like to ask, what is the purpose of curing them?? Will they cause problems if not cured?? I have about 10 in the tank right now, and didn't know they should be cured??
 
curing them releases anything they will leach, by not curing them you can have a spike in ph from the calcium contained in the concrete if i'm not mistaken,

with that said i have used way more than 10 at one time and have not had any problems, however i have a large water volume so if you have a smaller water volume i wouldn't use many at once,

the left over plugs you have you can put in a ziplock bag full of holes in the back tank of the toilet, they will be fully cured in a week or two.
 
silicone rubber. it was kind of a hrd process and i had alot of wasted silicone rubber but the end result came out pretty well
