I recently got an AquaticLife Mini Skimmer for my BioCube 29 HQI, but the pieces with the suction cups that holds the skimmer together won't fit in the filter chamber. The skimmer is cut in half and those pieces hold it together, however it sorta stays together on it's own, but some bubbles still escape. I want to hold it together more tightly with rubber bands, so my question is, are rubber bands reef-safe?
Thanks in advance!
