    Hello, i purchased a typhoon 5 stage reefkeeper rodi a year ago, i bought it with a 100gpd membrane, I see on the site you can buy 50, 75 and 100gpd membranes, i was told 100 is no good and will waste membrane fast, should i buy a 75 or 50 gpd membrane?

    The 100 and 150 GPD membranes have a lower rejection rating than the 50 or 75 GPD membranes. The max rejection rating from the larger membranes is about 93-95% where the smaller membranes get about 98%.
    The lower rejection rating means higher TDS will feed your Di cartridge causing that to exhaust faster.

    If you need anything else, please, don't hesitate to let me know! ;D
