I am running my 250w 10k reeflux also on the CoralVue eballast and absolutely love them. I have 2 single ballasts and both have ran fine for me for close to a year now. Don't think I'll ever run anything else. Plus our electric bill had dropped significantly.
i still need to get by your place and see your tank sue.
