Too Much Water Flow In 45L Tank?

[neilzomg]

Made a post earlier with a few questions but one that i haven't had any information on is the air pump...
 
When the pump is off the fish just swim about, enjoying life etc :L
 
whenever it's switched on its like the fish are being sucked towards the air stone and struggle to get away and eventually all three tetras end up in the corner where the air stone is and dont move away from it
 
The stone said it was for small aquariums and bowls... so i assumed it would be fine. Pumps out 75L of air an hour.

Sounds like your airline needs a control valve to control how much air goes through to the airstone.
Using these enables you to reduce the amount of air to suit your tank.
 
Have a couple of link here to show you what products you could use to do this.

Hope that helps.

So if i use like a clamp or say, Cable ties as i have plenty of those would restricting the air flow damage the pump?

Reckon cable ties could do the same thing but really would be much better using one of these clamps i linked you with, only a couple pounds for one of these. Not gonna break the bank! lol
 
As a side note, it is not absolutely necessary to have an airstone in a tank really, more like for decor than anything else.
 
As long as your filter does the job, agitates the water surface etc therefore making airstones not really needed.

Well i managed to find a clamp that's doing the job anyway! I know it mainly is, But i feel safer having air pumped into it

Got it sorted, Fish are actually swimming through the bubbles now as well probably was causing them stress too
