150 bucks is expensive for me, and it is mostly the cartridge price for a real RO/DI. When I am done school and working again I will start setting up a bigger system but for now I think this is a nice little DIY that can supply my 10 g with lots of great water for cheap. I am running a nano on a extreme budget so.....expensive is relative. So far diy stand, light hood, rocks and free tank/skimmer and pumps......extreme budget! Plus I love DIY!
