Review on 🐢 Zoo Med SZMTDS4 Turtle Dock – Enhances Your Zoo Turtle Habitat with Suction Cup Mounting by Jon Odom

I bought these suction cups to use with my Rena water filter system. As most aquarium enthusiasts know, the suction cups used to hold objects oxidize and harden over time, rendering them useless. I've searched the internet for replacement suction cups (and also checked out PetSmart) but couldn't find any suction cups that fit the large pins on the Rena clips. I read a blog on the internet that suggested these cups as a replacement and gave them a try. They work BUT it may take a bit of effort to get the needle into the cup (suggestion: soaking the cup in hot water to soften the plastic seemed to help). Once assembled they work as expected. I gave the product 4 stars due to the above complexity but I'm sure it will perform brilliantly for the function it was designed for. They are made of moderately soft plastic and stick very well to the aquarium walls.
