I’ve just purchased the 980aquaone aquarium(215ltr). Got it set up using stability and all the nitrate etc levels were spot on after a week. I put on some tetras ballon mollies and within 5 hours all dead. Think it lack oxygen as they were swimming top of tank. Have just put in an air stone. Any other suggestions on oxygen in tank this size.:
