It's important to add how much volume of water you use. If you use a massive amount of water and reducer, you can up the ampere. Also if you use a quick reducer vs. a rather slow one. And so on. Please tell us more. I'm happy to be proven wrong here.
For my 320ppm runs i use 1200ml of dw,2ml of electrolyte,0.5 tsp of malto, a starting temp of 65*C ending temp of 85-90*C .the run is for 59mins at 17-20volts, 1 tbs 0f gelatine.
for the last batch of 100ppm (used as a spray disinfectant) made i ran 5000ml of dw,6-7ml of electrolyte,0.5tsp of malto, about 20-28volts. run was for 77mins at 97-98mA. start temp was 26-28*C end temp was 32-36*C(measured with a laser therm bought from a discount store).the temp variation was from the 6 consecutive batches i made. I use a magnetic heated stir plate, All my production is in erlenmeyer flasks and for electrolyte i weigh 11gm of sodium carb and top up with 100ml of dw. most of my measurements are not strictly accurate but i get good results most of the time. When i mistakenly run at higher temps i sometimes get turbidity or opalescence.
