I have a friend who uses a high-end RO filter for his large aquarium. He recommended the Filmtec RO membrane (this is the same membrane he has) at a much lower cost than the high-end RO filters. The RCC7AK uses the iSpring RO membrane. While it might be just as good as the Filmtec, I'm going with the name brand reputable RO membrane for about the same price. The main difference between this (PH100/RO100) and the high end RO filter is the high-end filters use 1 micron carbon filters whereas the iSpring is a 5 micron carbon filter. My friends' need is to remove all chlorine from the aquarium water and you need the 1 micron filters to do that, per my friend... I'm super satisfied with the RO100. **Q: where do you get replacement filters for ispring ph100?** A: Hello, We apologize for the inconvenience, we will have them available by late April. **Q: In one of the bags there is a piece of angled plastic and three wood screws what does this go to?** A: Hi Evan, The screws are for mounting the system in your under sink wall. Some install them in wooden walls or use a piece of wood when mounting so we include those screws as well. Please reach out to our customer service team if you need further assistance. We're always ready to help. iSpring Water Systems, LLC **Q: Hello What is the drain flow rate valve 300?
