Of course, I didn't have sense enough to check the ammonia when I checked the pH and kh, but the ammonia now is 0. I salvaged what I could, and stuffed plants in my nanos, the fish are toughing it out and haven't lost any more. I had just purchased 6 rainbows, and they never even acted like it bothered them. Ovenmit, thanks for the offer of some moneywort, but until I get this straightened out, I'm just going to add a few plants at a time back into the tank and see how it goes. No point in melting some more! A little algae would have been a lot better than what my tank looks like now. Oh, well, another lesson learned, and it certainly won't be my last mistake, and my nanos look like beautiful jungles right now!
