i would say you might wanna consider a roDi on top of your whole house. clear water is KEY to having a clean tank!Next house will have an even bigger filter. We bypass the di for drinking water and to top off the fresh tanks so it gets used a lot.
Flow is another thing, I got the big gyre thinking I will run it low, same with return pump. Went one size up from what I thought I needed. It's ok, but I want more.
