Does anyone use or has used one? I have a sa2 Alke has brooder. I last used it about two years ago. It worked great BUT boy did it rinse gas. Does anyone know how much gas it will use per day? Or how long a 20kg bottle will last on average? Obviously this also depends on how high I turn it up I understand. Just a rough idea as ended up rinsing a huge bottle in a few days with the regulator on 3.
