DYI Chiller

Hello Folks

So I just got back into the hobby this year after taking 8 years off. I set up a 55 gal tank to introduce the hobby to my daughter. I live in a very old home without central air & I had to cool down my tank during the 1st mini heat wave early this summer, so I'm thinking about converting an old mini fridge I have in the basement into a chiller.

I've seen a video on U tube which shows coils/rolls of garden hose coming out of drilled holes out the side of the fridge wall (simple enough). However, I'm thinking 5/8 pond tubing might be easier to attach to ball valves and connect to a pump which uses the same tubes. I'm also worried that the materials a garden hose is made of might contaminate my tank in some unforeseen way. I'm also wondering if I should attach the DYI chiller to my existing old canister filter(s) or if running them though all that tubing/hose would tax their old motors or reduce water flow in the tank. Maybe it would be better to dedicate a new pump to the project. I do have an extra submersible pump in storage, but it's a small one (for fountain use) that may not be up to the task.

My main concern is how to connect this project/chiller to the tank & if I should buy a new pump, what would be a good fit (I'd want external if possible). Has anyone set up a mini fridge cooler and had a good experience with the project that could give a few pointers? Thank you for any information on this subject.
