Hi, my tank is little over a month old and and I used some live sand and bacteria to try to cycle it. About last week I tested the water and it was fine. However, I tested the water today and the parameters were: PH 8.4, Ammonia 2.0ppm, Nitrite .50ppm, and Nitrate 10ppm. My I placed in my Xenia last week and and it all fine until today. Right now, it's skinny and shriveled up a bit with little to no movement. What can I do to fix my parameters quick? I already did a 25% water change and added some Seachem Prime to detoxify the ammonia. Currently I have one clownfish who is very lively and a couple of blue leg hermits. Also, brown algae or diatoms I think have suddenly started appearing.
