I am currently cycling my 10 gallon tank for my female betta and 2 ADFs that I will get. It's been a week and the tank now removes all the ammonia I add to it everyday but the nitrates are rising fast. Two days ago they were at 10 and now they are at 30. I know this is a normal part of cycling and that will have to change the water to get rid of the nitrates, but how do I know when to do this?
Because my tap water is so bad, I'm using Ready Water for this tank which is pretty expensive so I don't want to have to do many water changes to get rid of the nitrates. How will I know when they have stopped rising and won't come back so quickly when I change the water? Also, after the nitrates stop, does this mean that my tank is ready for fish?
