patching dentate gyrus

I have been patching Dentate gyrus pyramidal cells and do current clamp recording for the past couple of days. I use Multiclamp 700B, pClamp 10.2 and K-Gluconate as internal solution. Whenever I patch dentate gyrus pyramidal cells, I can get 1GOhm seal but as soon as I switch from voltage clamp to current clamp, the cells are depoalrised to -30 mV. Does anyone know how to fix it?
