Hi all I am having 60 liters nano tank with 2oscellaris and 1goby and 1 cardinal, crabs and snails inside my tank. Ive switched to new skimmer bubble magus Qq1 at this Sunday. It still not foaming into collection cup and still bubbling at low. I adjusted with air controller with pump to adjust the air flow is that right or I will leave as it is . Someone can help me with this to get skimmate.
