auto water change thoughts?

[e46er]

So with my new tank upgrade Im wondering what peoples thoughts are on auto water changes?
i have an apex and the tank backs onto the bathroom which houses the HWT so I have access to easy plumbing and a space to store a 55 gal drum of fresh SW.
do you think the neptune DOS or a litremeter to run an auto WC is worth it? Currently I change around 35-40 gal every 2-3 weeks on my 120 I dont mind doing it to be honest but thats at a tank thats at home this upgrade is going to my shop which Ill be at probably daily but not hanging out at.

do you think a daily small water change is better than a larger bi weekly one? the " labour" is redundant since its not really a "chore" so strictly on a best for the tank success what are peoples thoughts???
