Which would be better for a 30 gallon? We currently use a vac and 5g buckets to do water changes. I always fill the buckets back up and prime them before putting back into tank. Ive never poured tap water without prime into a tank, I didnt think you were supposed to. So it is ok to use water changes and then treat the whole tank with prime after?
If so, whats the best brand water changer?
