20 c is temp of wort. Measured in thermowell of stainless jacketed fermenter. It cools by beer cooler through jacket and heats with aquarium heater. 20 is well below recommend max temp for US05 though. Its generally within 0.2 of set temp. max 0.3 difference. What would you recommend as temp, as that is easily adjustable ?

Cant find anything else to substantiate this.
Will cary on with the adjusted water as its beneficial in other ways and maybe in this way too !! Beer, science and a restless mind makes for a busy browsing history that doesn't have to be hidden !!!!
