I use a Cooler, Holds 12L, I fill it with 8L. I use a 150 Watt fully
submersible heater on the bottom of the tank, resting on a piece of sealed
PVC filled with rocks, with two -re drilled bubble walls on either side.
I'm in the process of creating holders from - plastic light cover grid , As
it is right now, I generally loose my board in the tank and have to go
fishing.
Looks like this, only red, cost about $13 at Target, (i use 1 for mask
stripper, and 1 for etch)
