Notes
Recirculation was a problem. Spray was slow and light although all valves were open. Tried to heat the wort, like a mash out.
Missed target gravity. Add 2lb dme to make up the difference. That could be the mash pH.
Ph meter was not giving reliable readings so mash pH may have been off. Was reading 10. Each reading g was different. Adjusted for 8 to try to be safe. Run off pH according to strips was low. Boil pH seems too high. Hot break was small, cloudy rather than big, fluffy clumps. Added 1 tap CaCl, hot break soon became as expected.
