Mike Paletta should spend more time on ReefCentral.

Randy has a pretty good article and this gets discussed pretty often.
Water Changes in Reef Aquaria by Randy Holmes-Farley - Reefkeeping.com
He goes over the differences between large batch, small batch and continuous.
Personally, I prefer automated "continuous" or daily changes for two reasons.
1) I'm lazy. So anything automated is a plus in my book. And small water changes are easier to automate.
2) I believe there is less stress on the system by doing very small water changes as opposed to large water changes.
I've been doing it this way for several years and I'm on my second tank with this process and it has worked out very well.
I originally set it up using a LiterMeter III, but now i use my GHL Profilux and Level Sensors in my sump. The latter never needs to be calibrated and it's the most precise. The system will put back in the exact same amount of water that it took out, automatically. All you have to do is set the height of each of the two sensors to approximately equal the amount of water you want changed out each time. The Profilux will allow me to perform the AWC several times per day. I choose to just do it once or twice. I have it set to change approx. 1% each time. So i've been going back and forth between once and twice per day (1%-2%). I think I only really need 1% per day, but I was curious if there was any difference if I doubled it. I'm not really sure one way or the other yet. Regardless, it's freakin awesome. All i have to do is mix a new 55g batch of saltwater every week or two.
My system is a 200g display tank, almost all SPS and LPS.
I have around 17 fish including several tangs and an angel. I feed kinda heavy once daily.
I have a display refugium, a frag tank and the big rubber maid sump, bringing my total water volume to somewhere around 350g.
Nitrates are always 4ppm or less and phosphates are anywhere between .04-.08 usually.
I don't use bio-pellets, i don't carbon dose, i even stopped using GFO. I do run ozone now and I still run carbon.
I believe my constant water changes, my Life Reef skimmer and my refugium are managing my parameters pretty well, along with all the live rock, live sand, and countless members of my cleanup crew.
Here's my mixing station on the right.
Freshwater on top (just for mixing up new saltwater), saltwater on the bottom.
There is a small pump in the saltwater container with 1/4" water line running to the sump.
And here is the empty sump where you can see the level sensors at the top right.
I have one mechanical and one optical. Will eventually swap out the mechanical for another optical.
The optical sensor is the "high" or "fill" sensor. When the water level gets back up to this sensor, the fill pump is turned off and the AWC is complete.
This sensor also controls the ATO, which is automatically disabled during the AWC.
The GHL Profilux comes with this AWC programming as standard. All you need is the two sensors and any pumps you want to use.
