Help with new system

I have currently build a 3 glass bottle system, Couple of question regarding hydroponics.

 

- Has anyone found a way to make the system/pump quieter? The plants are in the front room and it can be loud at times?

- I am currently using a timer, has anyone had any experience with how often the plants should be watered? I noticed that there are other systems on the market that also have timers, but have no idea how long/often to set it.

- Is it possible to put ‘underwater’ plants where the water is collected to clean the water? or would this in someway effect the other plants?

 

Many thanks in advanced for comments!
