After a water change the day before. So I changed water twice in a day and the nitrates are now sitting at about 20-40 ppm which is hopefully a survivable range for my orange neos and some hardy tigers. My white clouds have made it through all this unscathed.
Any reasons?
Basically what happened was I moved filters. I took a canister off my 40 gallon and dumped out the old water, attached it to my 12 gallon and started it up again. Next thing you know, bam 160 ppm nitrates. The nitrates in my Amazon tank were about 40 ppm. It is heavily planted so I am not too concerned there. Any ideas about how it hit 160 so fast?
