    Below are the specs for my Tap Water from my Cities Water Quality Report.


    Do you notice anything that makes this water a really bad idea to try and work with. I've been going for about 3 weeks now in my new tank using only this water and treating with Prime. I've considered changing to 75%RO/25%Tap which would bring m TDS down to 133ppm. My goal is a Non-Co2 tank with minimal water changes long term. Last week I started using Seachem Flourish, Excel, and Iron. Flourish 2x a week, Iron 5x a week, and Excel every day. I have some KNO3 and KH2PO4 on the way which I plan on dosing in small amounts 1x a week. My substrate is a 50/50 mix of Miracle Grow Organic Choice Partially Mineralized and Safe-T-Sorb capped with 2-4mm Gravel. There is currently no livestock in the tank, I'm still finishing a fishless cycle. I dose a little ammonia everyday to feed the bacteria. I'm currently showing nitrites off the charts so it shouldn't be much longer till it's done.

    Sodium here seems high.


    If you mix 75% RO, you'll need to add a GH booster to bring Ca and Mg back up a bit.

    Thanks for your reply. I did a little research into effects of sodium on freshwater fish and found this paragraph,

    If i do my planned 3/4 RO I would be at 36ppm on Sodium. That seems to be under the guidelines by a decent amount but still worries me. Maybe I'm just playing with fire trying to use any of my tap water. I was planning on using Seachem Equilibrium on the RO water by the way.

    My tap water is in the mid-30's. Doesn't seem to be a problem.
