Hi,
Thanks for the replies so far. At the moment there is 4 inch / 2 inch / 1/14 thick angle bolted through the floor at the front of the tank to stop forward movement, ( the tank is 640 lts fully baffled, but I only fill to 200 lt tops. This tank was custom made that big .... looking forward to the future) a full cage is in the process of being made up. I do run a veristream, if you look you can see the wires running from the pump to the controller. Thanks for the advice on the brushes. More advice welcome.
Many Thanks,
Paul.
