When I got Home from campus today I noticed that The zeolite crystals at the bottom ofv the tank are becomming much darker than what they were when they first entered the tank. I also Coducted another 20% water change, the water used was prepared yesterday (It was poured into a non-toxic container and left over night). The fish also seemed a bit restless but calmed down in about 15 minutes.

  1. The change in colour of the crystals reflects that they are taking up the ammonia - they will go very dark but we should change after about a month. The more frequent the water change they less the crystals will change colour since there is less ammonia in the water.
