This is my first, but I've been around them alot, and have been wanting one for years . . . .

I honestly have not, lets do that now.

1800 watt Heating element * 6 hours = 10.8 kwh
400 Watt pump * 6 hours= 2.4 kwh
Aquarium pump (20 watts?)* 12 hours= .2 kwh
100 watt drying pump * 6 hours= .6 kwh
160 watts of lights for say 8 hours = 1.3 kwh

Gives me 15.3 kwh * 6.9c /kwh =
$1.06 to make 40 gallons so 2.6c/ gallon Electric cost by my calculations. even if you say I'm off by 200% and it is still very reasonable.

Me either, see above.

2 days at this point; that's why I have 3 wash/ settle tanks now. The longer you let it settle, the better; I could probably get away with 12 hours no problem.

I have not stored any yet . . . . .
I am told that 1% D2 will kill any bacteria . . .. .

All questions are fair in my book, if they are not, then I must have a closed mind.

I don't get anything that looks like wax to me . . . . . . Maybe dissolved . . . .
I believe that soap and fertilizer are the primary (manufactured) byproducts. Basically you get Glycerin, water with crap + little methanol + lye in it . . ..
