I add all my media from my other tank but my PH is high running 8.1-8.7 and my Ammonia is rising it is up to 0.081 so I also have 0 nitrate and nitrite I do have a drip system going at 24G a day so I'm not sure if I am having a complete cycle or just a mini and the drip is taking care of it. My Ray seem be doing great eating like a pig. But my Arowana and 2 Jacks are only eatting 1-2 bits every few days
