    Muratic Acid

    I just added Muratic acid and did a test of my TA right after that. The numbers seemed way off? Did the acid screw up the test or something?

    You need to give the acid 30 minutes with the pump on to mix into the water before doing any testing. If you didn't do that the reading could easily be off.
