(i posted this in the equipment section as well, i just wanted to get your attention specifically too. what do you think?)

Im in the market for an RO/DI unit and looking for the best possible unit. My only question is what is the purpose of having 2 DI resin housing vs 1?

the two units i am looking at are:

$ 199.00 - OCEAN REEF + 1 FIVE STAGE 75 GPD RO/DI

VS.

$240.00 - OCEAN REEF + 2 SIX STAGE 75 GPD RO/DI

Is the extra DI housing worth the $40?

Sorry we lost contact with our forum page for awhile. Two DI housings give you better control of your DI use. Once you see an inch or two of color change in the second housing we rotate cartridges. Moving the second cartridge to the first position and refilling the old first stage and putting it in the second position. That way you always get zero tds and have maximum DI filtration.

Thanks for the order
