The top float is controls a NC relay which will keep the system from pumping out all over your floor ( catastrophic failure, as you'll lose your res contents and potentially your plants, as well as attracting a lot of attention from your downstairs neighbors) by killing power to the feed pump if an over-high water level occurs. Failure is caused by calcification, built up nutrient salts, organic material, or debris blocking the upward movement of the float. Just flick it w/ your finger once in a while to make sure that it moves ok.

The low float kills power to the return pump if an overly low level occurs. Less important, IMHO, as a failure could only result in the roots sitting in nutrient until you discover the problem- low O2 in the root zone, but nobody's calling the cops)

Waterfarm 8-packs come in one box. Multi's are usually a truck ship, what w/ that big ol' plastic barrell. You probabley want to pick this up somewhere, as opposed to having it delivered to your working address. Another option is to buy the controller and a couple of the extension packs, and score the plastic barrell on your own. I know I can pick up the same barrell for $10 at our local pickle factory- free sometimes. They smell like pickles for a long, long time though. Will ship cheaper, and more discreetly.

Either system yer gonna need a bunch of hydroton as well, which is another pricey ship. Try to pick it up from a retail shop if ya can, or get a binding shipping quote before you choose your vendor

Umm- neither of these is a dwc system. Multi's an ebb-n-flo, WF are recirculating drip.

Either will fit under a K, configured properly.
