I am new to Marines. I would like to change my fluorescent T8 tubes to the Arcadia T8 LED tubes. I have a Fluval Roma 200. I have been told that as long as I have magnetic Ballast this is straight forward swap. I rang Fluval and she said it is magnetic but I have seen other forums were people are saying it is electronic. Can anyone help please as these tubes are £45 each ,so a lot of money it they don't work.
