Okay. Starting a journal of the progress of my new tank and how long it takes to cycle. Basic info on my tank is: 29 gallon tank, 2 filters, fluval 206 canister filter and fluval aquaclear 70 hob power filter, artificial plants, glofish black gravel, hydor koralia circulation pump, and fluval vueTech 200 watt heater. I let a cup of tap water sit for over 24 hrs and these are my initial parameters: gh 161.1, kh 125.3, ph 7.4, ammonia 0, nitrite 0, nitrate 0. All tests were done with api test kits. Not strips.

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?
