Double Water Change... Safe?
I'm doing daily water changes in an attempt to reduce NitrIte in my new 20-gal freshwater tank. The tank has been running for a total of fourteen days, and fish have been in it for ten. Ammonia is under 0.25ppm, but NitrIte has been 5ppm or higher for a week. Today, I did a 40% water change and saw no measurable decrease in NitrItes immediately following the dilution. Note that there are no detectable NitrItes in my tap water.
Is it safe to do back-to-back water changes on a single day? Is there a minimum interval I should wait?
