Red Sea reefer shooting white gunk debris everywhere

[newhere]

Hello my Red Sea reefer G250+ whenever I turn off the return pump for feeding or maintenance or even water changes and I turn it back on stuff like white poop and debris flies everywhere does anyone else have this issue or now how to fix this?? I have been draining water from where the return pump is to hopefully catch it and take it out before but when I turn the pump on it shoots all of the place. I have been putting a filter sock over it to catch it but its kinda tetius with how my set up is with the lid

I have seen this happen when bacteria start to grow inside the piping. The bacteria slime is dislodged by the water bouncing through the pipe. With any luck, the corals will enjoy the bacteria you have as a meal but I have also seen tanks crash when large cleaning operations have stirred up the bacteria flock that was growing in the system.

Some newer pumps ramp up when they start up, and that might reduce the amount dislodged? Hopefully as this tank matures the problem will fade away?

Have you found a fix to this?? I have the same issue. I have just been putting a small filter sock over it to catch the debris bit is tedious with a rim.

Could try cleaning the return pump and then (before a water change or with a sock to catch it) cycle the pump on and off until most of the debris is gone/stops coming out. Of course this would only help until the gunk builds back up again (assuming that's what the issue is).

Or, hypothetically, are you dosing anything into the return chamber that might be precipitating out/causing sediment buildup? Either precipitating out when the flow is off (by that I mean you are turning the pumps of during specific dosing times and the lack of flow causes precipitation) or precipitating out/causing sediment build up little by little? Back flow from when the pumps shut off could be mobilizing it and stirring up the return chamber before the pumps are kicked back on. . . ?
