I've gone through half a dozen types of Bubble disc available from Big Al's and various LFS in Canada. None of them are to my liking...they either don't stay upright goes upside often and or the bubbles are as fine and full on the disc. I've seem some pretty amazing bubble disc here where they are black and the bubbles coming out of them are very fine and the disc "seems" to stay upright on the tank bottom...
Any suggestions and recommendations? want to best of the best.....
