I have a 90 gallon tank and a brand new EHEIM PROFESSIONAL 2026 placed under the tank. I unplug the EHEIM before I do a 30% water change but after I fill the tank back up do I have to push down on the big priming button on top of the EHEIM before I plug it back in or do I just plug it right back in?
Thanks for any help in this matter.
