I have two questions number one what can I do to keep my suction cup on my DIY filter from coming off the glass? I don't want to use magnets or silicon as the metal in magnets might be harmful to the future fish (still cycling) and then I don't want silicone as I want to be able to take the filter out if needed. My second question is will this rock thing be safe for invertebrates and fish? This is the link for the rock thing:
