nuvoskim dc protein skimmer help

[jamie]

hi guys so i have a 30 gal tank. with 6 gal refugium.
i have
2 clowns
1 chromis
1 cardinal
1 fire fish

1 emerald crab
2 snails

2 anemoes
3 zoa colonies
4 ricordea mushrooms
3 torches

now ive had the skimmer since june. i hardly ever have to empty it, maybe once or twice a month. now when i try to lower it the cup will end up floating up and the bubbles escape via the sides of the cup. is it normal to have to place something on top. i would assume no. any ideas. i feed a cube every other day, then a pinch of flakes in between the cubes. thanks

Skimmers can go crazy.
Often when something dies. Maybe a snail. Have you counted your fish?
But it can be contaminants on your hands. Did you wash with soap and not rinse quite enough?
You definitely get it when adding some chemicals like Chemiclean

But is it normal, no.

No experience with that skimmer. Maybe a video and or a picture would help us help you. Doesn’t sound normal tho

so the bubbles will push the cup up then once the rubber stopper lifts up, the bubbles escape out the side, instead of going up through the collection cup. its been doing it for a long time. its almost as if not im running a skimmer due to the lack of waste being taken out. been testing my water once a week. think ill go woth out the skimmer for a bit, and see if anything changes

Have you taken the skimmer out and given it a good clean ? I know that HOB and AOI skimmers get a lot of gunk stuck in places they shouldn’t be and could be blocking something inside the skimmer.

So is the only adjustment the height of the cup or can you control the speed of the pump and or air intake as well?

just the height of the collection cup

So then why does it have a dc pump I wonder?

Try adjusting the rubber seal around the cup of the skimmer down the throat of it and make slight adjustments from there. Weekly maintenance would be a good form of knowing if there is build up in the Venturi. Nano stuff gets dirty fast

Mine sits high due to the water
