Step-by-step
Step 1: Wipe inside glass with magnet cleanerMove slowly in overlapping passes. Drop the inside half briefly to dislodge stuck particles. For tough algae, lift the magnet inside the tank to engage harder rubbing surface.
Step 2: Use algae scraper for stuck-on algaeHold blade at 45° angle. Push slowly. For glass: metal blade is fine. For acrylic: ONLY plastic blade - metal scratches acrylic permanently.
Step 3: Clean exterior glassSpray white vinegar diluted 1:1 with RODI water on a microfiber cloth (NOT directly on tank - splashes can hit livestock). Wipe in straight strokes, not circles.
Step 4: Remove calcium/salt creep on rimsSaltwater tanks accumulate "salt creep" on rims. Apply vinegar with a cotton swab or cloth. Wait 2 minutes. Wipe with damp microfiber. Avoid getting vinegar in tank water.
Step 5: Polish acrylic carefullyFor acrylic only - use Novus Plastic Polish #1 to remove minor scratches. Apply tiny amount to soft cotton, polish in straight lines. Test on hidden corner first.
