I started up a saltwater aquarium over 3 weeks ago. Tank is 120lt aquaone 620.
I set it up and the following day got 8 kg of live rock, a few days later got another 2kg. Tested my water after a week with API kit and got PH 8.2 ammonia 0.5 nitrite 0 nitrate 0. A few days passed and levels stayed the same so I bought the Red Sea mature program, after a few days nitrite and nitrate spiked (5.0 and 80+) but ammonia was still 0.5, 2 weeks has now passed since starting the mature program. (Last Thursday nitrite hit 0 and nitrate 20 ammonia stayed at 0.5)did a few 25% water changes over the past week and levels didn't change at all! On Sunday LFS
said to get a fish so I got a black chromis, fed it yesterday. Yesterday nitrite went to 0.25 everything else stayed same. Today I have tested and ammonia is still 0.5 nitrite 0 nitrate 10 and PH 8.2.
Any ideas why my ammonia just won't go down?
Here is the instructions for the mature pro program I have been following - http://www.marineaquatics.co.uk/shop...e-pro-kit.html
Any help would be appreciated!
