Ricky D Posted January 23, 2021 Share Posted January 23, 2021 Hi guys, I have 4 tanks, all planted and all different sizes. I have been running all between 6-3 months. I did a 30% water change on the big tanks (40&29)and topped off the smaller tanks (20L with 3 guppies & 10 shrimpand 3 gallon with 7-10 shrimp). I did the water change on Wednesday and tested the water today (Friday) and I have ammonia at 0 but nitrates at around 60- 80 on all tanks. I did dose with ez green on all tanks. Is this normal or what can I do to bring down my nitrate? thank in advance Ricky Link to comment Share on other sites More sharing options...
FrozenFins Posted January 23, 2021 Share Posted January 23, 2021 Do a waterchange and floating plants will help too. Link to comment Share on other sites More sharing options...
