FYI: pH Up is a VERY expensive packaging of soda ash (sodium carbonate). It's sold in grocery stores as washing soda as well.

Alternatively, you can use 20 Mule Team Borax from the grocery store to raise pH. It has fewer side effects than soda ash, and is safer to handle.

pH Down is a VERY expensive packaging of dry acid--can't remember the chem name but there are lots of generic brands of dry acid. Or you can use muriatic (hydrochloric) acid, available at most hardware and tile stores.

Total Alkalinity Raiser is a very, VERY expensive packaging of ....BAKING SODA! That's right, it's the same as Arm&Hammer sodium bicarbonate.

"Liquid Chlorine" is usually the same as ultra bleach or a double strength version of ultra bleach. Sometimes it's more expensive than bleach, sometimes cheaper. But you can ALWAYS use ordinary bleach.

See? We just saved you a TON of money going forward!
