Temperature Control during ferment

[scogan]

I have a pressure regulator that fits on the gas side of the keg and have tried fermenting under pressure. The issues I had and not sure how to address were dry hopping and sediment in the bottom of the tank.
How did you address those issues?

I have only just started fermenting in cornys and serving from the same one .Floating dip tube bypasses the sediment .Dry hop either using magnets ,opening it up and purging ,or transfer to another vessel .

So here is my ispindel graph from corny keg in 5 gallon bucket with 2 gal of water and fishtank heater.As you can see even during the vigorous start (OG fropped 40 in 36 hrs ) there was no problem with temperature rise and until I cranked it up around day3 it stayed on +/- 0.5c from 20C. A good result and first time I used an ispindel.
