@lockman yes, the filter was fully cycled its been running for about 2 years. I cycled this tank 2 years ago it's just recent that I decided to do a rescape because of the move.
No, it is still safest to test it first after adding ammonia (fish food) to make sure as 2 weeks is a long time and the bacteria may have starved and dropped way off. Was it still in water during this period?
