Hey guys, I am running a 100 gallon tank, high tech with heavy CO2 injection and a daily Seachem Liquid Fertilizer routine. I use nothing but RO water at 20% per week. I just bought a TDS meter and it read 430. I'm curious, is it normal to have such a high TDS with Seachem ferts in the water column? I tested my RO and it's at 006. Everything in the tank is healthy including Otos, Shrimp, etc... any help would be appreciated.
