@reefloat Has very kindly offered to donate an AWC26 unit, with the funds going into the pot for running this place.
Here's the blurb from the auction:
The Reefloat AWC 26 Litre Automated Water Changer cuts out the need for numerous containers, mixing pumps, manual syphoning and all the mess that goes with it! Example: this unit will give a 10% water change on a 232 litre setup. This AWC26 is being donated by reefloat.com to reefbase.co.uk, a UK based marine hobby forum. The forum doesn't display ads and doesn't have a sponsorship model. All product suppliers are there for free and so there's no bias or obligation in discussions about products. The forum is funded by donations by members. The funds from the sale of this AWC26 go directly to fund the forum. By acquiring the AWC26 via this auction, you will still benefit from the same great support and warranty that's offered by Reefloat, who will ship your product to you directly. Reefloat: AWC26 Shipping charges to be confirmed. International will likely be more.
It's a 10 day auction.

10% of the proceeds also go to the British Red Cross.
The auction may be revised with certain details, so bear that in mind.
These brilliant units normally retail at an already reduced price of £147.20.
