So i have been doing weekly water changes since my tank has been having an algae problem. I have noticed lately (past week or so) that the sand has been a lot dirtier than normal. So before my water change today i tested the water and my ammonia is high it looks to be just below 1. The only thing i have changed is that with the last 4 water changes i have been cleaning my filter (sponge carbon ect) regularly in the old tank water. Could this be causing it? Should i consider removing it completely? Nothing has died recently
