Return pump having white substance discharge?

[smallbutmighty]

Hi guys, not sure why everything I off and on the return pump it will have white substance discharge...

I also notice that after that it will stick on rock or on the coral..

All this I believe it came out from the return pump.. I have check the piping nothing in it... Could it be in the cooler system?

Any want could share your encounter to this experience before?

it could be the detritus build up near or inside the returm pump... it could also be calcium carbonate precipitate build up due to dosing...should be inert and harmless just tha an eye sore.

you could put filter sock to cover the outlet of yor return first for a few second to trap the detritus..
