The holidays are a busy time of year, and it’s very likely that you’ll be spending consecutive weekends, or even entire weeks, at the homes of friends and family. Obviously this means you won’t be sharing your holiday joy with your aquarium livestock, who have all but been abandoned as you sulk from house to house. Fortunately, with all of the different aquarium controllers and smartphones that infect our daily lives, you can keep a close eye on how things are going with the aquarium. With these controllers and phone apps, you won’t be returning home to a surprise disaster in your aquarium. You can get a readout of a variety of water parameters, see what equipment is still functional, and even perform some basic aquarium tasks all with the push of a button. Just make sure your nephew playing with your phone doesn’t think the aquarium app is a game, otherwise you probably will come home to a surprise.
