Auto Water Changes

[frannypanny]

Hello fellow reefers!

My question is regarding auto water changes.

I realize that this will change based on the bio load... But what is a general rule of thumb for how much water should be changed daily in a 150g reef tank?

Thanks y'all!

My goal on my 125g is about 1.5% daily. So I do around 2 gallons a day.

I think that is up to you how much to change. I have my 100 gallon setup to change 1.4 gallons per day.

I've set up my Auto Water Change tank. Salinity and Alkalinity are spot on at 77 degrees F. I have an 80G reef tank and running Apex DOS for the water changes. I will be doing .85 gallons of water change every day. Curious if you guys run a heater in the water change tank?
