I have a 55 gallon tank I am going to cycle (I've had fish before) but I can't seem to get the water to stop being murky. I used basic sand from Home Depot for the substrate. I've done 3-4 %100 water changes and it's still murky even after running the filter 24 hours. I thoroughly rinsed it before I put it in so I really don't know why it would be this way still. Any thoughts?
Thanks
