How would I rinse with dechlorinated water with the tanks? Also can I do pots, pvc pipe, and rocks this way or should I bake them?
Let EVERYTHING soak. 24 hours.
Use a cup of bleach for 3 gallons (it's not exactly 10:1 ratio but close).
After 24 hours. Drain and pour fresh tap water in the bucket. Let everything soak again.... about 6 hours. Then drain and fill with fresh tap water then add water conditioner and let everything soak for a few more hours or overnight again.
After the filter media soaks in the bleach/water, I would rinse it in fresh water in another container and squeeze and agitate it in fresh water every couple of hours, changing the water each time. Then add fresh water, water condition and let is soak (while periodically agitating it) for a few hours.
For the tank I would make a small bowl of 50/50 water and bleach, take a towel (one that you don't mind that's going to damage it), and scrub the inside of the tank everywhere. Then rinse with clean water. Fill with water, add water conditioner and let sit for several hours. Drain and you're done.
