Sourdough

Okay so I neglected Cleatus for quite some time in the back of my garage fridge maybe 9 months. I felt terrible and apologized and made a promise to him that I could save him. I took 1 tablespoon fed 50g flour and water discarding half twice a day for 8 days before he started to build much volume.  Around the 8th day he doubled his volume and then some in 12 hours.   He will now pass the float test in about 10 hours after feeding. I have changed his feeding schedule to once every 24 hours. He remains on the counter and the house is between 68 and 72 degrees.
