Well, its been three days now since one of my ballasts for my 29 Biocube stopped working properly. Im really fed up with Oceanic Systems because i've made several phone calls as well as written an e - mail and still have yet to be helped. The damn woman on the phone always transfers me to warranty no matter what i say and i always get a voicemail (customer service at its finest). Anyways im not exactly sure whats wrong one ballast will power each light in each socket but the other will not power either light but the fan will activate if i use it. And actually it has turned on the light a few times but only momentarily. Does anyone know where i can get help...? And also i've been considering ditching the top all together and getting a 20 inch Sunpod 150W fixture, has anyone done this, and do you know of anyway i could keep a closed top, because i have cats.
