Ok it's day 12 and my Ammonia is still hitting 1.0-2.5. I've been changing water daily for the past 5 days 20-40% each day. Then adding more salt, de-chlorinator with the good Bacteria. The one fish thats in there looks fine, I removed the 4 Koi 3 days ago in preperation for the new fish. The water is still looking a but cloudy, not nearly as back as before I started changing the water, but it's still not crystal clear. I've also added about 5 plants to help out. I thought the Ammonia cycle would only last 5-7 days? Not to mention I'm using old gravel, driftwood from an established tank. Should I be draining the water to 50% or more? Will this Ammonia level go down soon? Can I add fish during the Nitrate spike? As long as I do regular water changes? I sure hope this Ammonia goes away.
