One of the best tools we can use in our aquariums to help clean algae from equipment is a toothbrush. Yes, we’re talking about that free plastic thing with all of those smaller pointy things that you get at the dentist. The bristles are rigid enough to remove even the most stubborn of algae and calcium buildup off our our equipment, but also small enough to get in those hard to reach places. They work well on cleaning the intake strainers on water pumps and can even be used to remove algae directly from live rock. And if you want to get fancy with it, you an even tie a toothbrush onto the end of a long stick to get those really hard to reach places without getting your arms all wet.
