Pretty easy method.

But many love the gas........
I agree. Just do EI but much less. 1/2 to 1/4. Change water by the same ratio, more or less. Meaning if you do 1/2, water change ever 2 weeks.

If your tank can get away with no Excel but you still use it consistently, you can really go pretty long without ferts. I have done plenty of tanks that were about 1/8 of regular EI dosing or just waiting to see deficiencies because I can be lazy with low tech. It can take a long time, depending on mostly lighting.
