Don't get me wrong, I loved running the biopellets. Fed as much as I liked, never had detectable nitrates. If I had been at home when the skimmer pump went down, I could have turned off the pellet reactor and not have had a problem. I am just going to try it without. Heck, I might go back to running them if I have trouble keeping nitrate down once I get a larger fish population. But I will try to figure out how to better monitor and get help if needed when out of town.
