Need help with DIY hose for tetra ex 1200

[Margimargi]

Hi guys. I DIY some hoses to my filter but the problem is, the water doesn't have full flow, instead there's a little air space between. It makes filter work very loud.

Should I buy oginal hoses? I don't think they would be any different since the hose is perfectly fine. May there be another problem?

You don't need original hoses, you just need to get the air out of the system. It might have a slight leak where the hose clamps are, or the air could be coming in from somewhere else.

Thank You for a reply.
I was working hard to make sure there's no leaks and things are bond as tight as possible... I'll re-do those hoses again at weekend tho, just to make sure.

May the long hose be the reason? It's kinda long goes around the whole stand

The length of the hose shouldn't make any difference. If there is air in the system, it is leaking in from something and hoses don't normally leak. It's normally at the joiners or o-rings around the motor.
