Another thing to point out is the comment was regarding those 2”(?) diameter frag pucks instead of just using the regular plugs. Yours to my eyes looks to be on a regular plug and not one of the pucks. To each their own I guess. Didn’t know there was a correlation between frag size and plug size though.
Yah i had a few frags shipped on the larger ones, they had no plug on the bottom they were just a disc and my urchin kept knockin it off of the eggcrate. >< I eventually just glued it to another frag plug so it would stick in the egg crate.
