my DIY frag plugs

what do you guys think of the DIY frag plugs and disks? the larger plugs are 1 1/8" with a 3/8" stem, smaller plugs are 3/4" with a 3/8" stem. the small disks are 1 1/8" large disks are 3 1/2". I have made 2 5 gal buckets full of plugs and disks so far. i'm thinking of also making 2" disks and i'm working on a way to make square tiles.

 

The disk pictured is 3 1/2" I haven't made any 2" ones yet

 

Portland cement and reef sand same thing as DIY live rock and I'm 99% sure its the same as other name brand frag plugs

 

I was thinking about it and I would have to make it the same way as square tiles which would require me to make a silicone mold which is kind of expensive. I'm actually thinking of making these plugs and disks as a little side business and if I do I might be willing to spend the money to make the molds

 

i dont have time but i'm greedy so ill make time LOL just kidding. its just another way to support my aquarium habbit that i'm addicted to

 

i went ahead and made a mold for 2 1/8" disks. here is a picture of them along with all the other sizes i can make
