how often should i change my water now that im having readings of ammonia,nitrite and nitrate?fish-in cycle.
5 rosy red(fathead)minnows
live and artificial plants
several hiding places
white gravel about 10 pounds
HOB quietflow filter as well as a DIY moving bed filter
dont wanna loose the fish.i know they r cheap feeder fish which is 1 reason i use them but i want to keep them in with my male betta once cycle is complete.i dont want to mess the cycle up so im not sure how much of a water change and how often i should do it to keep them and the cycle alive. :)
