Stresso, Tank stress Options

[CHLeong]

Hi Bros,
Would like to share with everyone what I am doing and investigating. I have been trying to understand the differences in environment for goldfish raised in a pond and tank. Noise is one area I am looking at and I understand that noise/vibration multiply many times in water media.
I am no scientist so feel free to rebuke my discoveries. As we understand that generally fishes react to the environment via their lateral line. So I placed my ear against the wall of my tank, and realised that they are living in a very noisy envirnoment. Vibration from the internal water pump, air pump, the sponge filter are generating a lot of noise. Its like blasting a mini compo in a bed room(tank) as compare to placing in a park(pond).
Bros, put your ear to your tank wall, off all equipment and realise how peaceful. Then turn on everything, do you find any difference?
Attach are pictures which I have made to reduce the noise in their environment.


I am in a middle designing a less stress tub for my fishes, that I will also share with everyone.

Comments?

Hi, recently i bought an airpump to make some green water.
as the air pumb has 2 outlet, i connected the spare one to my goldfish tank. When I do that, notice that there is a very large noise (like the air pump is inside the tank) when i press my ear against the tank.

Want to know whether this is ok? will it stress the goldfish (currently having 5 ranchu in the tank)

Rgds.
