I will whip out the duct tape then and strap on the power head. In my little pea brain it seems like overkill to turn over all the water 20 times in an hour, but I will defer to the experts. I need to work on why my HOB doesn't work. Haven't mixed the salt yet as I didn't want to run salt through my backup filters. I've got them churning on the tank now to filter out the dirt and debris from the sand. I was disappointed that the salt didn't come with any measuring cup of any kind. The implication was almost that it's designed to all be used at once. Oh well. I grabbed an old betta cup and made my own so I'm good.
