Hi, guys! I have been having absolutely no problems with my tank for weeks. I am making water changes almost every 3 days (at least 25% sometimes more, depends on my patience) always cleaning the substrate a bit and all. Then about every 10-12 days I do the major change, cleaning algae etc. However, I did a big water change on Saturday, and Sunday morning the ammonia was almost between .50 and 1.00 and nitrates were at 10, no nitrites. In a panic I did another 75% water change, and left. Sunday night I check again and ammonia was between .50 and 1.0, and nitrates at 10. I did another 75% change. This morning, same thing. But this time I did a 95% water change, rinsed the filters and vacuumed the substrate. This was at 11 am. Now, at 7 pm, ammonia is again between .50 and 1.0... I give up.... I don't know what to do. Oops, I didn't think to change the nitrates this time. I'll do it and come back, but I am guessing they're the same. HELP!!!!
