Hey everyone so yesterday I got a a used Marineland 100 protein skimmer and I put it in and got it running but I seem to be having 2 issues. First it's making a type of sound as if it's pulling crazy amounts of air in which makes it kind of loud, like a woushing sound almost. I've read people say it should be silent. Second it only seems to be producing white micro bubbles from the top I haven't seen any brown nasty stuff start to build up. Although I did read this could take 4 to 5 days I just want to make sure something isn't clogged or not working correctly
