beginner to beginner talk:
i was always told to not go more than 50% wc (which is considered a big water change)
And I feel you are overcomplicating your water change technique. I,for one, simply pass a garden hose through a window, connect it to a syphon and let the it do the rest. Filling up is a bit different for me since I have a big water tank on the roof where water sits at least a week.
If this is your first big fish it is going to be overwhelming at the beginning but quickly you'll "learn" your tank and fish and you'll kinda instinctively know what your tank and fish need. Have a look at my thread "first arowana" for example. lots of stupid questions asked there. That's how you learn.
