How do I choose a freshwater aquarium cleaner?
Start by matching the cleaner to the job and your tank. You'll want to use gravel siphons for substrate and water changes, algae scrapers or magnetic cleaners for tank walls, and chemical cleaners only for disinfection outside the tank. Check compatibility with your tank's materials and inhabitants, and make sure tubing length and suction fit your tank depth. Look for sealed magnets, rust-resistant parts, and fish-safe formulas with clear dosing instructions.
What materials should I look for in a freshwater tank cleaner?
For acrylic tanks, it's best to use nonabrasive pads or acrylic-safe scrubbers. Avoid metal blades or rough scouring surfaces. If you have glass, stiffer pads or scraper blades are fine. Tools that go in the water should be rust-resistant stainless steel or aquarium-safe plastics, and magnetic cleaners should be fully sealed to avoid corrosion. For siphons and tubing, choose clear, kink-resistant, food-grade vinyl or silicone that's sized to your tank depth.
