Ok am really new to the hobby . At the moment am starting a 50 gallon bow front for reef am 5 days into a fishless cycle .my question is ,Do i have to run my bak pak hang on skimmer all day or turn it on occassionally? And do i even need it on during the fishless cycle. Sorry this is probally a dumb question. But since i have been a member here i have learned so much and am confident hat am in good hands when it comes to questions about my up coming build.
