question about remora skimmers

[ryanfish]

It creates bubbles via a spray injector (i think). I have a remora pro and it stops skimming whenever I put my hand in my tank, when feeding or adding kalk or magnesium. Takes about 10 minutes to an hour to start up again. If it takes takes to long to bubble or doesnt bubble at all then try lowering the collection cup or try cleaning the spray injecor with the brush it comes with (pipe cleaner)
