I really wish you would make more videos, out of all i have found i enjoy yours the most

[GreenLearning]

@wisyakman I Do plan on making more videos. There are so many possibilities. I guess I just need to pick one and do it. Stay tuned!

[GreenLearning]

@wisyakman You can count on it!

How do you vent the nitrogen by using a bladder tank? Could you teach me how to make the special vent on top of the wellmate tank?

[GreenLearning]

@bengapuz It is NOT a bladder tank. Its a tank made to vent gases using a float valve. They are used on wells to blow off odors from sulfur ect. This valve is removed and its connecting pipe shortened to about a foot long. It will no longer function as a pressure tank, but it will let oxygen dissolve into the water and vent off the nitrogen that will not dissolve. Its a blow off valve and the wellmate people can hook you up.

[bengapuz]

@GreenLearning Ok got it, will inquire with wellmate here in the Philippines if they are carrying the blow off valves. Thank you for sharing your knowledge with us. Take care.

Why did you quit posting?

[GreenLearning]

@baddogonline very busy with major changes in the entire structure of our lives, but more will follow.

Instead of all that extra pumping and filtration, why not just create an aquaponics system? That gravel tray would be a great place for the plants.

You could even just grow duckweed and feed it back to the fish.

This would naturally filter the water and add oxygen.

[Zeclectic]

Ahh, I see from your other videos that this is what you are doing. It still seems like you could make the system less complex and require less electricity.

Have you considered using a wind pump?

Also, instead of that oxygenation machine, why not have a series of cascading waterfalls for the water returning to the pond to go through?

[GreenLearning]

@Zeclectic My outdoor system is one pump and a few tricks to get extra oxygen from the water moving. It runs on a very efficient pump and can produce fish at the cost of .87 each including the cost of feed. The indoor system is required to keep tilapia alive over winter. If fish were raised to maturity in the indoor system the cost would be $4.20 each for energy and feed.

@Zeclectic High stocking densities require a lot of oxygen and bio filtration. Having up to 400 pounds of fish in a 300 gallon tank, there is no way they could live without some serious oxygen. So, it all depends on your designs and goals for the system.

Duck weed can work, but you have to grow a WHOLE LOT of it. I prefer to grow water spinach or other fast growing green in the grow bed.

That's impressive. What hp submersible pump are you using? Is it efficient?

[GreenLearning]

@msredneck001 1/3 HP and no its not really efficient. Its just an over winter system.

Awesome.
