Push process Ilford delta 125 plus medium format

Hi! I have developped my first roll ever today...!!! I´m preatty impressed how it came out..I took my Lomo Lubitel 166+ for a spin today, came back home and used some developper for Ilford I dont know exacly wich one .The film expired like 2 years ago so I developped 7 minutes instead of 6:30 what was suggested. Temperature was 21.5° C degrees.Then I wash it with continuos water for like 10 minutes and did the fixed bath for like 7 minutes...It worked out preatty good!!! As long as I dont have a scanner I can´t really post my pics...Now I wanted to try some push processing or any other suggestions would be apriciated...!!!Thank you..

Chef, Have fun playing around and push processing, etc. And save every negative. I think your ten minute wash before fixer is way to long--a minute or so is plenty. Be sure to wash the film for twenty minutes to half an hour AFTER fixing. And, again HAVE FUNE!

Thanks a tons!!!! that´s a cool tip...like under running water 20-30 minutes? for push process I have to develop like more like 10 minutes and what with the fixing and so on...
