Hey guys, We're pretty new to the fish community. Our tank is almost 8 weeks into its cycle, and we've had no spike in nitrites, no increase in nitrates, and no real decrease in ammonia. We're doing a fish-in cycle (local pet shop said this would be fine with minnows, as they are hardy, I feel bad for the poor fellas at the moment, with the ammonia levels ) We're doing at least 50% water changes every 2-3 days, giving time for the bacteria to grow, without letting the ammonia get too high. We are adding Prime with every water change, as well as Stability. Our tank is 21litres (about 5 gallons) and we have 7 white cloud mountain minnows in there (as suggested by pet shop.) We have a trickle filtration system, with carbon cartridges (320L/hr). We're concerned that we are 7-8 weeks into the cycle and our parameters haven't changed since the first time we tests the water (about 6 weeks ago, been doing weekly tests). We bought our own water test kit (API master kit) two days ago, so have been doing daily tests since then, to monitor ammonia especially. This is a picture of today's water tests (in order: ammonia, nitrite, nitrate). Any ideas on why the parameters haven't changed? and how can we help our tank to cycle, so our poor fish don't have to live in constant ammonia? Also, anything we should really keep in mind considering how new we are to keeping fish? We really want happy and healthy fish Thanks!
