good movie lol!
I think the walmart stones are actually one of the best quality because they don't rely on 'glue' to hold the nozzle on (which often leaks giant bubbles). I have the best results with these.Hard to beat the dirt cheap walmart pumps. Air stones all suck, if you can get the no stone thing to work for you go for that. I'm trying lee's discard a stones, but they still haven't arrived. I'm hoping they will perform as well as the expensive air diffusers (don't get clogged, ever) after I weigh them down with stainless steel nuts. I'm sick of constantly clogging stones.
