i have a 75 gal tank which has been set up for a little over two months. i have cycled the tank and added the protein skimmer today in the sump. i have noticed that the return water pump is shooting in small bubbles back into the tank since the protein skimmer and the return pump are very close to one another in the sump. should i be concerned? will these bubbles slow down once it starts doing its job? thanks, brian.
