I do changes everyday because i believe it keeps all my parameters more consistent. If i change out 37 gals in one shot, my parameters will change much more drastically and it makes it harder to know what amounts to dose etc.
Yes, I use a refractometer. In fact I have 2. I calibrate once a month. I am consitently at 1.025. I check the tanks and holding tank, as I have the apex/tunze doing the topping off of the evaporated saltwater every hour, 24 hrs a day. The water is all run thru the refugium, so it mixes well, then to the sump and back up to the display.

Well, you get a much higher turnover of water and export of nutrients by changing 16% of water every 3 weeks, instead of that same amount doing 1.75 gallons every day. Plus creating a lot of work for yourself. Ideally, should change about 20% every 2 weeks.
