I actually checked yesterday and in the day time and I had a reading of 0.04. Now i have to find a way to maintain it. I did slower down the flow coming out of the dual reactor. I’m in the process of buying some chaeto(can you believe people actually charge for this. Something there gonna throw out anyway). Hopefully I can it to grow. Never had any luck with it. Just trying to figure out ways to combat these dinos. Tank starting to look unsightly
