So i just ordered the apollo v tube for my main set up and also ordered a carto tank. From what ive been reading a dual coil will trip the amp safety feature so ive been looking for some pre-punched HR 35mm cartos with a flange (if possible). Any advise on where to get one? Or maybe im looking for the wrong thing? I just want to keep that safety feature off and get an actual VV. HELP!!
