Here is my auto-mixing station that also does the daily water change automatically.
All I do is dumping salt (2 boxes capable of providing 200 gallon mix) at the upper tank every couple months or so.
I use 1 EB832, 1 PM2, 1 cond probe, 1 breakout box, 2 pmups, couple powerheads, 3 RO solenoids, 2 float valves, 2 recirculating pump, 2 filter socks.
2 float valves are connected to my RO line and installed on the upper (brine) tank and lower (1.025 SG) freshly mixed tank. They are turned on by 2 solenoids.
1 solenoid is installed in the siphon tubing from upper tank to lower tank.
One pmup pumping freshly mixed water to my display tank for 1 hr a day (15 gallon?) and at the same time one pmup (connected to the EB832 at the display) pumps old water out of display.
While doing water change, apex also turns on off the siphon solenoid to drip brine into the lower tank and turns on off solenoid to let RO into the lower tank depending on the SALT reading by the probe. That way, lower tank is always at 1.025 SG. The solenoid to let RO into upper tank is on during water change.
So, there is always about 30 gallon of freshly mixed saltwater ready to serve.
There is a heater (set to 72F) that so far never got turned on.
There are multiple float switches, overflow pipe to detect / avoid emergencies.
There is a pump pumping water from lower tank to upper tank so that I don't have to manually do it for some occasions.
There is another pump at the lower tank pumping water into a 7" filter just in case there is any precipitate of any kind.
Tanks are 40G breeders. Shelving is from Home depot (or Lowes). Overall maybe $700 at most. When manual water change is eliminated, I enjoy reefkeeping (or fishkeeping) a bit more.
Just wanted to share and if u see any issue or anywhere I can improve, please fee free to comment...
