which ro unit to get?

Hello All,

The flow rate that I use is about 1 gallon per hour. That is significantly below the rated flow (which is 10 gals per hour), but the water quality is a little bit better with slower flow rates. I just plug in the TWP when I get home from work and turn it off before I go to bed. Also, you can use warm water for DI.

As for recharging....strong bases and acids are used to recharge the TWP. When bases and acids are mixed together (in correct proportions), they cancel each other and form a neutral (pH=7) solution.

Note that eventually you will need to buy another TWP cartridge because you always loose a bit of resin (those green/yellow/purple pebbles in the TWP) while recharging or during normal use.

For those interested in a even less expensive water conditioning....I have heard of some reefers using regular tap water as top off water. This only works if you have really clean water or if you drip your top off with kalk. Kalk is suppose to precipitate phosphates and minerals out of the water.
