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!
The Nitrogen Cycle Cycle: your fish produce ammonia. Beneficial bacteria live in you filter media (one reason why filtration is so important!). The bacteria take the ammonia and convert it into nitrite and nitrite into nitrate.
