My elbow grease is taming runners from plants that invade the spaces allocated for other species, and wiping down glass to remove green dust algae. I dip my co2 diffuser in 10% bleach for 10 min every 2 weeks. I wipe down my glass tops and plastic trim every week to avoid any "aquarium buildup" that might occur. I truly don't understand how people let things get out of hand, like when I see a tank completely covered in algae. The tank didn't get like that overnight, it took weeks of neglect before they took a picture and asked for help. By far the easiest thing to do is trim plants and add nutrients.LOL and he still hammers that home today! But that's not what people hear, as let's face it it's not as interesting as discussing dosing in minutiae.
