Bakki Shower / System Aeration

Recommended Posts

That cooling system would also put quite a bit of Oxygen in the water as a bonus...

 

I recalled the above post by syzmic, early on. It was in response to THIS POST, where I was talking about "bakki showers". (I wasn't sure of the proper name for them at the time. I learned that later, while doing additional research on Aquaponics Systems.)

 

Anyway, I was looking over the system today - err, yesterday (it's 12:32am here). Between the return pipe entering the sump from the moving media filter and another return from the deep water culture beds, I am pretty certain that quite a bit of aeration is happening there.

 

Obviously, until I get a DO (Dissolved Oxygen) meter, I will be unable to confirm the actual amount of oxygen that is being introduced into the water. But, it has to be quite a bit of air, 24 / 7, from those two 2" pipes.

 

What I am getting at here is this. Once I am able to add a bakki shower to the system, that, along with the water return pipes to the sump, should inject more than enough air for the fish in the system tanks, even if they were heavily stocked. So, I should be able to completely do away with the air pumps in the fish tank. Then, I could just have an emergency air supply for when we encounter power failures. I already have a simple relay system that will sort this for me.

 

My goal here is to lower the power consumption of the system. I have let that get a bit out of hand.

 

4 LED lights

1 system monitor

2 water pumps

2 air pumps

1 programmable timer

1 16" table fan

 

I would like to try to get my mains power usage under 150 watts, if possible. If not, get as close to it as possible.

Over on the Cebu Forum we have been chatting about using a $3 Arduino micro-controller to do something like "read air temperature and control a cooling fan".

 

It could do all the above stuff too!

 

Or you could use a separate Arduino to do just the above.

 

Either way, you would need to define the "rules of the game" - what inputs to read, what calculations or decisions to make from those inputs, then what to do about it - what to turn on/off, how fast to run them, when, how long for, etc.

 

Then write a software programme to do implement that.

Build a prototype, test it, fix any problems and then assemble it in a final form.

 

Sit back in a comfortable chair, pour a cool drink and watch it automatically doing it's thing! ;)
