resun FR problem

[davidluvfishes]

Hi i am using 1000ml Resun FR for tunze silophos. But i cant seem to get it working right. When i try to on my 1200l/h taiwan powerhead , it produces a motor rattling noise and water seems to flow out very slowly. The silophos in the FR also seem to be stuck , not moving within the mixture. Wats wrong?

How to place the sponge given as per purchase?

hi,

Maybe you got media stuck in the center inlet tube and motor cannot push out water.

This is what I did:

1) push into the bottom two sponges.

2) push 1 sponge into the top cover.

3) insert the cover and stick the end of the tube into the sponge.

4) With the the of the center tube inside the sponges at the bottom push the top cover aside and fill in the media.

5) Screw in the top with out pulling out the center inlet tube.

hopes this help.
