Get you a restaurant grade trash can with lid (home depot) $25.00-40.00, all plastic float valve (ebay) $7.00, spiggot (ebay) $6.00, 200 watt heater (ebay) $16.00, & powerhead (ebay) $20.00.
I can give you pics of my setup. Works perfect. When you first mix your salt in the trash can for first time, keep track of how many scoops of salt you used to reach the desired salinity.
Well worth the investment. Congrats for a good buy.
