high phosphates

Hey all, I finally got the money to spend on an RO unit, and hoping I didn't make a mistake. There's a lot of phosphates in my tap and even worse in my tanks, so after a while I've decided to buy a RO unit. I got RO buddies 3 stage system, and I'm kinda confused by the output. The TDS is lower...

I've been hesitant to dive into any of the higher end acros due to my system sitting comfortable around 0.12 to 0.18. I was wondering if anyone is growing acros that aren't the easier ones (slimers, torts, etc) at higher PO4 levels?
