First post from a newbie in Adelaide, hi guys, great info!. I started making my blue-bowl last week after watching a u tube demo. I was scratching my head on what to use for a centre cone and I have been experimenting with a 50mm plug and waste, but it needs way too much work. The funnel idea is genius. I'll be trying that for sure. I picked up a 1050 LPH garden feature pump at Bunnings for around $40 after reading that 2 gallons per min was a good feed rate. This weekend looks like being in the shed. Hopefully I can add to my 0.5 grams panned so far.. Thanks to all, I'll post my results in a few weeks
