Automated Water Change

I recently tore down my 30 gallon reef tank and am setting up a low tech planted tank instead. Reusing some of my saltwater equipment I think I can set up a half gallon automatic water changes daily. Using a dosing pump and Auto top off. Would also us the dosing pump to dose excel daily and thrive once or twice a week. Coming from a reef, was hoping to make this as low maintenance as possible.

My question is: Is there any benefit to doing small daily water changes in a planted tank? Or would it be more of a hindrance, taking nutrients out of the tank? Was thinking of dosing excel and thrive in the am right before lights on, then doing the water change at night.

It depends on your bioload and how planted your tanks are. If you have a massive bioload and your plants can't take up nitrates fast enough then increase your autochange schedule to more frequently. If your nitrates are perpetually low then decrease your water changes or increase your fertilizer regiment.

I believe frequent daily water changes in low tech are more of detriment than say weekly water change or every two week's.
Dosing fertz can be once a week in low tech NON CO2 = less fertz needed.
As plant mass increases, maybe twice a week for fertz.
Assumes you are looking to keep thing's low maint.
Only fishes I have ever performed daily water changes for in nearly 40 yrs were a group of juvenile Discus.
