when does a water change become irrelevant

[Proteus]

So in the last month I've launched zeo and tm balling. Switching from prodibio to zeo I had a po4 increase but thanks to the people at the zeo forum I'm down to. 08 and dropping.
With zeo and tm balling I should have zero nutrients and water should be topped up on the big three plus trace.

So what's the point of a water change at this point? I haven't stopped my routine only slowed it down from 10g a week to 5g

I think water changes dilute and replace so many things we can't account for, they never become irrelevant. I attribute the success of my tank to large frequent changes, and would never consider not doing them.

I don't want to stop doing them just unsure if it is doing any good.
I have a habit of doing water change before adding new livestock. Just makes me feel as if it's better water

I agree. But this then suggests you think the water in the tank is of lesser quality?
I'm certain of the fact that changing water does no harm (with exceptions of course) and I notice the tank does better than any previous tank I've had where I did less frequent changes, so for me, it's the most important thing I do.

Yes prior to zeo and dosing I did believe the water was lesser quality
I'll continoue with the water changes as like said does no harm

A big part of zeo success is weekly water changes I thought. I have been doing zeo and ballin and still doing 100 gallons a week. The way I look at it is I don't want to sit in the same bathtub for months

Nothing beats a nice water change; tank feels so fresh

Stop changing the water once the tank has been emptied.

I am not balling so I have no knowledge of it, but I can't see how you can go without.
