Inspired by the design of jefferskn on the reeftank. His design can be viewed here
http://www.thereeftank.com/forums/f2...on-167510.html
so i attempt to make my own with a little tweak so i need everyone input. Here is the layout for it (i hope you understand my drawing)
The difference between my design and jefferskn is that i am going to use two pumps. this way later on i can use float switch, salinity probe with controller to automatically fill the water from RO/DI to mixing station.
I also put more ball valves so i can swap powerheads and drain water easier.
Please let me know if you see any flaw or redundancy in my design.
Thanks
