A friend of mine gave me a CPR bakpak skimmer, only problem is the powerhead burned up.....and he threw it away....including the parts to make it run on the bakpak, will I have to order the parts?....I've read about people using maxi jets on them, are they good to go?....or would i still need the parts, also what powerhead do you recomend, it's the orginal bakpak, thanks
