Hello I need advice I have a 75 gallon tank and it's been cycling for 8 weeks. I did a 90% water change yesterday but it has never fully cycled, my NO2 levels has always been high. What should I do now? Should I add more NH3 or let it sit for another week? My NH3 levels are about 1ppm and I know by now both NH3 and NO2 should be zero Thank you Kayla
Hello! So I'm relatively new to fish keeping. Because of REALLY bad circumstances, I have ended up with two single tailed fish in a 10 gallon tank with a 29 gallon tank that I'm planning to move them into eventually. What I want to know is, how can I cycle my 29 fast and safely? Should I leave the fish in the 10 and do a fishless cycle on the 29, and then add them once it's cycled? Or should I just add the fish and cycle the tank with them in it? I have a 400 gph hang on back filter with filter floss and ceramic media. Thanks!
