Jtrch38 Posted July 17, 2021 Share Posted July 17, 2021 Need some expert help here. I am pretty well versed in planted aquariums, cycling, and keeping shrimp, but this one 20L tank is driving me insane. It still has not cycled in 3 months. I have successfully done 3 other fishless cycles in three other tanks that are thriving, so I’ve got good knowledge of the nitrogen cycle and things like that. This one here though 🤬. Everything thing seems to be growing nicely and looks healthy but tank just won’t process the ammonia. PH 7.4 Ammonia 4ppm Nitrite 0 Nitrate 10 GH 179 KH 71.6 Temp 78 Eco complete planted substrate Remineralized RO water Planted Fluval 207 canister filter with Biohome biomedia Only difference in this and my other tanks is this has a canister filter and eco complete substrate. I have tried EVERYTHING. Biological booster, Dr Tim’s One and Only, Fluval Cycle, Tetra Safe Start, and Prime with Stability. Nothing works. Test kits are good. API and FLUVAL. Used old media from cycled tanks too, nothing. Does ANYONE know why this cycle is not progressing? Link to comment Share on other sites More sharing options...
