No, but my Biocube 32 is the newest one. Bought it in September or October 2020, so it definitely doesn’t work with that one lol.O wow I haven’t come across that yet did they specify in any previous articles if that’s for older or newer bio cubes it would be interesting to know I have some small bubbles on my rock but I don’t see any coming out of the return into the tank
