Need help! Air stones vs Micro-Pore Air Diffuser

Can anybody help? I am currently setting up a new bubbler setup and was going to purchase airstones for the setup when I say the micro-pore air diffusers. Does anyone no the difference in these? Is one better than the other? I would really appreciate any input you guys have. Thanks

do you mean an air curtain? air curtains work like air stones but they are make of plastic and dont stop up like the stones do.

Yeah I believe so It was made from plastic. Are these better than airstones

IMHO they are way better. i used air stones when i first started hydro and it took about 2 months for the air stones to stop up. i cleaned them by blowing them out with 120PSI airtank. ive been useing the curtains since then. and never had any probs out of them other than i had to tie a weight to them to hold them down in the res. they have some lil suckion cups, but the dont hold long at all.
