Summer hits and tank maintenance slides. It happens every year — water changes get pushed back, glass goes unwiped, and algae starts creeping in. If you’re going to let anything slip, make sure your cleanup crew is picking up the slack.

Cerith snails are one of the best investments you can make for a low-maintenance tank. They work every layer — substrate, glass, and rockwork — eating detritus, cyano, diatoms, film algae, and leftover food before it can fuel a bloom. They’re nocturnal too, so they’re putting in work while you’re not even looking!
