when does a water change become irrelevant
 

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 :wink:

Nothing beats a nice water change; tank feels so fresh :mrgreen:

Stop changing the water once the tank has been emptied. :twised:

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

Holy smokes! 100 gal a week? I can't even imagine changing that much water....

Takes about 5 mins :razz:. Thank god for controllers
