Update - water mixing station
Update - water mixing station
I have been taking things slowly so not much has changed in the main display. I am amazed that the display has shown virtually no signs of any nuisance algae. My refugium on the other hand is a mess of slimy green stuff, clinging to the walls of the fuge (although not on the live rock I have in there) and in a small chaeto basket I have suspended in the fuge. So far so good.

I have also had the tank up and running for a few months now and have done virtually no water changes! This is not on purpose, but I have been working on setting up my salt mixing station for automatic water changes. I'm almost there.
I covered this in an early post but the system works like this:
Water goes from the RODI unit on the wall, directly into a 35 gallon fresh water tank that sits about 6' off the floor on a stand above my frag tank (20 long).

This tank serves 3 purposes. First, it supplies the display with RODI top off water. I put the tank as close to the ceiling as I could and the small Tunze pump can push the water about 6' up into the sump located directly above this room. The water enters the sump via a Kalk dispenser container that is located in the refugium section of my sump.
Second, it supplies the 20 gallon frag tank directly beneath it with RODI top off, delivered via a float switch. And finally, I can turn a ball valve and fill my salt water mixing tank, or fill small containers via another ball valve attachment to the plumbing leading to the mixing station.

From the bulkhead of the 35 gallon fresh water water tank, the plumbing runs to a spout just above the first of the two tanks on the left side of the room.

The tank on the left is a 25 gallon tank for mixing salt. I can then fill the tank on the right (55 gallon capacity) which will supply the display upstairs with salt water at about 1.5 gallons per day. I wanted to be able to mix water without affecting the stable source feeding the tank. I can add 25 gallons quickly from the RODI 35 gallon tank, leaving 10 gallons in the tank to ensure that the fresh water supply for frag and display remain unaffected.
Once I hook up the AWC via the litermeter 3, I will use the water I drain from the display to add to the frag tank. The frag tank has a nano overflow so that the water entering the 20 gallon will displace about 1.4 gallons into the sink per day. The frag tank is mainly for quarantining new frags and my hope is that the water chemistry will stay very close to the main display. This should make transfers easier once I have dipped and observed corals for some period of time.
I also set up a small fragging shelf in the room. Its a tight fit as the fish room is a small utility room off my garage, but I love that I no longer need to do any maintenance or testing in my display room. I can now test water as it it drawn down via the AWC, cut frags, etc.
