I am no expert but I can tell you what I do for my nano tanks, 2-5 gallons. That is 50% water change every 3 days and daily dose of a couple of drops of Excel and TMG since they are on the higher light side. This works for me, but may not be the ticket for someone else. I like to keep DOCs low and like water changes for all my tanks, big and small.
This regime works for me with my tap water that is on the moderately hard/alkaline side.
The "proof is in the pudding" so to speak, so I would adjust this routine if I noticed deformed or chlorotic leaves, lack of growth or poor fish health. Treat the tank/plants/fish, not the test kit, I always say, lol.
