mavis,i had one of those exact ones go bad.the company that makes that ballast for coralife,doesnt make them any more.thats why theyre on backorder.i believe central aquatics in now coralifes new name.if you go to the site of www.oceanicsystems.com go to contact us,and email them they will send you a ballast for free if they have any left in the warehouse.oceanicsystems is part of coralife.
Well I am still trying to locate the ballast. These guys don't return phone or email messages.
Does anybody have a damaged setup and want to sell the ballast?
