Peninsula 25 return chamber not getting enough water

[obreefer]

Hello guys, I recently bought a peninsula 25 from my local shop. It was fine until return pump which was included with the tank started to have problems as there was not enough water in the return pump area, this caused air bubbles and loud noises which I have been trying to solve. I don't think its because of I don't have enough water as the filter sock keeps floating up. Could someone please help me

I can’t see the video although it sounds like not enough water in the system

Based on the video. Your water is ample but the pump is too strong. Use the flow adjuster on the return pump to slow it down. Its pumping water out of the return chamber faster than it can come back in.

Can do either of the above.

Unlikely the pump will outflow the overflow weir. I would just add more water unless the display level is quite high, in that case turn the flow down.

Its more then likely that either the pump is too strong, there isnt enough water in the system or something in the filter chamber is restricting flow to the pump.
