I did a tank cleaning on my 10 gallon tank, I bleached the filter intake and plastic plants and rinsed thouroghly. I also changed 50% of the water and the filter cartrige. My 5 platys were sick and dying and it finnaly came to me that i messed up the fish cycle. It's been 2 weeks since That big clean. I took a strp to test the water today and found my nitrates were 30. I dont know the ammoinia. So what phase i'm I in? What do I do next to fix the water cycle?
