what to do???

[sea gnome]

I have a 250w pfo ballast that I bought in Jan. from JL and when I was in Winnipeg last week I went to Jayson and picked up a 20k Radium bulb which willl not fire on my balllast. Jayson states that many people use them on reg. pfo ballast. JL says they don't work on them. I am wanting to know if people are doing anything to they ballasts to make them work or am I just having more of my dumb luck?? Since it doesn't run I am left with the dilenma of buying either a blue wave (dual) or two elctronic balllasts or getting rid of 20K bulb. Money is a concern but at the same time I want to be happpy with the outcome. If I do go with the new ballast(s) would anyone be interested in pfo ballast??? Or on the other hand, would anyone be interested in brand new 20K radium bulb??? Thoughts and suggestions gladly received. Rachel
