Thank you. I also started out dosing buckets now I dose for the tank.Also, to your question about dosing. If you're treating the volume of replacement water in the bucket, dose for the volume of the bucket. If you're treating for the volume of the tank, dose for the volume of the tank. I do water changes with water coming in through a hose from the tap, and I dose Prime to the volume of the tank. I used to use buckets, and dosed for the bucket.
