hello all.
i have been looking to get 8 flat ceramic airstones for my auto tray.
but the same air stone can range from £5 - £40??
they all claim to be the same....blah blah blah.
does anyone have a ceramic airstone? an can you share some light on why some are cheap and some are more expensive.
or does it even matter?
HELPPPPP !!!!!!!!!!!!!!!!!
