I'm afraid using water from your father's tank will do nothing to help cycle your tank. The bacteria we want to grow live tightly bound to surfaces not flaoting in the water. But media from your father's filter would do the job nicely.
If your father has been keeping fish for 40 years, has he kept up with advances in our knowledge? When he started, there was no such thing as fishless cycling. Back then you set up the tank and bought some fish and hoped they survived. We now call that fish-in cycling, which is no longer recommended. Instead we now grow all the bacteria the tank needs before we get any fish, and we do this by adding ammonia from a bottle to simulate fish waste so the bacteria grow. The link I gave you explains what I mean about this type of cycling, and it is possible your father won't know about it.
If you father would give you some of his media - and he can lose up a thrid without harming his fish - and you put that in your filter, it would give the cylce a good kick start, and considerably shorten the process.
Do you intend having live plants in your tank? These also help speed up the cycle.
The Eheim biopower filter contains sponges and this stuff called substrat pro. The sponges are cleaned by squeezing them in old tank water that you take out during a weekly water change, and substrat pro is washed by swooshing it round in old tank water. Because it is small balls, if you empty it out it takes ages to collect all the bits again so I leave the balls in the basket and swoosh the whole thing, carefully so no balls escape.
Another filter I have used is the Eheim Aquaball. This looks like the biopower filter but it contains just sponges. It is a good filter for smaller tanks - another one to think about for your tank. Also look at the Fluval U series filters.
