Holly brown tide I stopped dosing phosphorus and did a 50% water change and the drown tide came rolling in hard. My Ottos have all died in the last 2 weeks as well. I'll be restocking the Ottos as soon as I find some. I have a Phos-zorb pad in the HOB and it looked like it was then drown tide WTF.
I need to find some Amano and Ottos
I don't know where I'm going but I'm on my way.
