HOLY CRAP Maxi Jet
 

if anyone has the upgrade for maxi jet 1200 ( the upgrade that makes it force out 2200 gph) do not i repeat do not put them on a wave maker with the use of the big impeller the other end of the impeller will burst through the back of the housing... if it's on constant flow it's fine but not alternating... if you want to use the alternating pattern of a wave maker you must use the smaller impeller that comes with the upgrade i will post pics of the damage

Well that sounds pretty cool! I want to see! :D

i bought the kit jl sells and the big propeller keeps blowing the mj right off the suction cups, but im gonna buy 1 or 2 more kits since i already have the mj1200's and the mod actually makes them do something

OUch...sorry to hear that Tom. Would like to see pics of what happened though.
