skimmer is sending out little bubbles round the tank, is this right?
Sorry to be a pain, im quite new to this and am after some advice. I have just purchased a 63lt tank with a v20 skimmer. I have set it all up, put the water, sand and bacteria in and have left it for 2 days. The skimmer is sending out little bubbles round the tank, is this right? If so will it always be like this?
Thanks for any help
