Active Aqua AAPW550 Submersible Water Pump, 550 GPH, 33W, 6 Ft Cord
feeding a hydroponic-style chiller, circulating a tub that has no hose ports, pumping a tub out into a utility sink
An upright folding tub with an insulated lid, sized to pair with a small chiller.
A basement tub has two jobs: hold the cold and stay out of the way. This VEVOR is an upright barrel 31.5 in (80 cm) across and 29.5 in (75 cm) high with a listed capacity of 90 gal (341 L). It stands on support tubes with an inflatable ring around the top, and the listing describes a foam layer in both the wall and the lid. When the floor is needed for something else, it drains through a side pipe or a bottom plug and folds into its carry bag.
What the listing does not describe is a pair of ports for a chiller, so a chiller’s hoses go over the rim and the lid sits on top of them. There is no filter either. Mind the weight when you choose the spot: a full tub is about 750 lb (341 kg) of water before anyone gets in.
Tip: Sweep the floor before you unfold it and fill it only about two-thirds – your body takes up the rest, and grit under a full tub is how punctures start.
