I will be back in a week and cleaning out my storage unit. I have 2 closed loop VFD's that are turn key. If you need flow for a big tank nothing is better than these. $200 each.
Also have a monster Volcano skimmer rated for up to 4000G. $800

Maybe a long shot here but I have the following things left over for sale.
1/2hp VFD closed loop pump and controller $200
3/4hp VFD closed loop pump and controller
These are in great shape. If you are running a big tank and need tons of flow these will be the best cheapest way to do it...
