Eheim Class 350 vs Fluval 205

[hypnogogia]

Is the noise air bubbles or is the impeller knocking against something? They're very different sounds. For the former, tilt your filter a little in different doreciotns to get air expelled.

For the latter, open up finer and check the fittings for the impeller. Again, I'm sure all of this will be in the instruction manual somewhere.

It was the air bubble. But I think I have fixed it, by bringing the pre filter sponge in the intake pipe down by few CM. First picture it the sponge was literally touching intersection pipe picture second its slightly down. I still didn't understand how this can cause air bubbles. Now the only noise is mechanical sound of motor, which is fine to me. Sorry I haven't cleaned the tank, I don't have the time to clean it before the weekend.

I am changing water of this tank every night

Why?

But what is causing this trapped air? Could it be cause of the pre-filter sponge in the intake?

Could be.

Why?

Could be.

Its a new tank and I think soil is releasing a lot of ammonia hurting my DHG

Next week I will reduce the water change to twice a week and then eventually once a week
