The manufacturer recommends changing the water at least once a week with a chiller, more often with heavy use, or every 3 to 5 days without one. The tub manual also asks you to consult a pool supply store before using pool chemicals, to let them dissolve fully before anyone gets in, and never to add them to an empty tub, and it notes that damage from improper chemical use is not covered.

The manual warns that alcohol, drugs or medication before or during a plunge may lead to loss of consciousness with the possibility of drowning. Go in feet first, keep breathing steadily without holding your breath or hyperventilating, and get out at once if you feel weak or lose control of your hands, arms or legs. Prolonged immersion below 70°F risks hypothermia, and core temperature can keep dropping after you get out, so do not drive or operate tools or heavy machinery straight afterwards.

Stainless is the finish some buyers prefer for its look, though the guide notes the polished look can be a challenge to maintain, and it does not recommend stainless in coastal regions.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/details\u003e\n      \u003cdetails\u003e\u003csummary\u003eDo I need a chiller with the stainless black barrel?\u003c\/summary\u003e\u003cdiv class=\"dcbs-fb\"\u003e\n        \u003cp\u003eNo. It works as an ice bath on its own, though with no filtration the tub manual says to keep it covered and change the water every 3 to 5 days. A chiller cools and heats the water, filters it through a 20 micron cartridge and runs ozone, and the manufacturer then recommends changing the water at least once a week, more often with heavy use.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/details\u003e\n      \u003cdetails\u003e\u003csummary\u003eWhich chiller size, 0.8 HP or 1.0 HP?\u003c\/summary\u003e\u003cdiv class=\"dcbs-fb\"\u003e\n        \u003cp\u003eBoth are the SY-PRO chiller on the same 120 volt, 15 amp dedicated GFCI circuit. The manual’s reference cooling rate is 1 to 3°F every 40 minutes for the 0.8 HP and every 20 minutes for the 1.0 HP, so the 1.0 HP roughly halves the wait. It draws 12.8 amps against 11.3 and weighs 88 pounds against 68.5.
