if you want some thing easy to maintain i would strongly recomend purefreedom Why very basic and simple to maintain' no bells and whistles I've had a couple of set ups can't fault them so if any thing should go wrong 9 times out of ten you can fix it on site👍
My DIY system (650 ltr) was super cheap, it earns me money every week.
If anything goes wonky, i installed it, so 99% of the time i know what it is and how to fix it
