Have been using an RO Buddie for over a year and recently acquired a Kent Maxxima 24 GPD with a spare canister, several carbon and sediment filters and got to meet an older reefer which was fun. Sadily I think I will have to replace the DI and RO membrane as the unit has been sitting likely for about a year. Found replacements filters on Purewater4u for about $75 but when I purchased it the seller thought it was the 50GPD and I chose to not bother returning it as he is out of state. I know within the next 2 years I will want a larger tank but questioning whether I should sell off the Maxxima and get a higher output BRS unit adding about $100-150 in extra cost or keeping the Maxxima and replacing the cartridges... Any advice? Is the Maxxima a solid RO/DI upgrade from a RO Buddie 50 GPD?
