the degasser is saving me tons of DI. I knew my well water was bad, but coming out of my RO filter I am getting around 14TDS, given my input water is in the high 900, I’ll take it! Even with the 14TDS coming out I was only getting maybe 55 gallons on 1 anion DI canister. After testing my CO2 in the water it was off the charts which is why I made the degasser.
my degasser is just a 65 gallon brute trash can with a degassing tower.
The tower is what the RO system fills up and then it just dumps it into the Brute trash can using RO tubing to Backup float valve.
the blue RO tube that loops up goes to the float valve, the one that hangs to the bottom is the feed to the DI stage.
In the tower are two airstones powered by a cheap air pump. That is on 24/7 just because it used so little power I don’t care that it is on.
Inside the brute trash can I also have two giant airstones (pictured above). Those are powered by a huge pump I bought on Amazon.
That one only runs for an hour in the middle of the night because it does use more power and is loud enough to hear when not near it. I am not sure if I actually need that, but I figured more air can’t hurt.
After all of that is done my CO2 in the water is either 5ppm coming out of the degassing tower or undetectable if I let it sit overnight and let the large airstones run once.
The RO system on/off is controlled by my Apex. I have a solinoid and a low/high optical sensor. So that I do not have TDS creep, it only turns on when the low sensor is dry and turns off when the high sensor is . The float valve is my backup in case the solinoid fails.
To get the water from the degasser through the DI resin and to my holding tank, I use a delivery/demand pump.
I use the smallest/slowest one they make.
This then pumps the degassed water from the brute through my PRO DI resin and into my storage tanks.
Those are about 25ft from my DI resin which is about 10ft from the degasser.
the demand pump has a pressure switch similar to the ones used for booster pumps. I have a similar high/low setup in my RO storage container that is attached to a solenoid. When the solenoid closes, it causes pressure to build in the DI containers and the demand pump turns off.
After all of this my DI resin now lasts me about 250 gallons.
Before the RO system I have a dedicated iron filter because my well is very high in iron, after that I have a softener followed by a bubble removing chamber (this is just so the water isn’t bubbly coming out of the tap, it serves no cleaning purpose.)
After all of that I have water that will hopefully support my reef hobby!
I hope I answered your question
