So i bought a little aquatics 50gpd unit 2 months ago knowing its the best but thinking it could get me by maybe 6 to 8 months so i can get a proper unit. I noticed when i flushed the filters it was 3ppm but settled to 2ppm which annoyed me but dang close to 0. Since i have built two tanks with all dry rock and sand. Today i did phos checks and then decided to check my rodi water and it came out as .12 ppm phos. So obviously the rodi isnt working adding to my phos.
My question is, will a better brand bigger rodi work to get rid of that extra ppm? Should i get the one with two DI membranes?
