If you're doing a daily water change, how many gallons are you changing out daily and what is your total tank water volume? Some say 1%-2% is ideal.
My total water volume is around 200 gallons. I change out 3 gallons from 10 pm to 6 am using Apex Dos pumps. I do it while I'm sleeping because they can be pretty loud (tank in living room). That brings me to my next question. Benefits of changing out water slowly over 24 hours vs an 8 hour period? I have a mixed reef with a decent amount of SPS.
Has anyone played around with different water change amounts? Anyone notice a difference? What did you notice? I use to do 4 gallons a day (2%) and could have sworn everything looked a little better but maybe I'm just going crazy.
Do you do larger monthly water changes as well? I personally stopped doing giant water changes. It would always lead to a small swing in parameters which made my corals cranky.
I have searched a few other threads. Some good info. I'll link below in case you'd like to read through it. Randy Holmes says he shoots for 1%. Curious on everyones experiences!

doing daily auto water changes? what % do you change?
how much do you change daily? I’m not asking about whether it should be done or the net reduction of “whatever” contaminants? I just want to know the percentage of total water volume per day and how you reached that number. For example, I am changing out 19L (about 5g) per day on about a...

Poll: Water Change Frequency?
Water changes - a topic discussed in great detail throughout R2R. Should we do them and why? How often? How much at one time? The questions go on and on. Well this thread/poll is meant to answer only one of those questions - How Often? I'm more curious as to the frequency of those that...
