Hello everyone.
I have been noticing this white-ish clear sort of slime in my return pump area. I'm not sure but I think it is coming from my biopellets.

The biopellet discharge goes to my skimmer section of my sump and then through the bubble trap and then to the return.

P.S. There is also quite a bit of foam.

Any advice or info would be appreciated.

Looks like harmless bacteria, probably caused by your bio pellets. I dose carbon and get the same thing. It's the trade off we make for the higher bacteria population.

Thanks for the quick response. I kind of figured that. I guess I'm just going to have to clean my pump a little more often.

+1 on bacteria. My sump has quit a bit if it as well.

Good to hear I'm not the only one :)

I got that after a while of vodka dosing. No3 got to zero before I realized it I forgot to cut the dosage down. I sucked it out with solution but it kept coming back within days. Once I cut down on the amount I dosed, that finally went away.
