Review on Boyd Enterprises ABE16755 Chemiclean Liquid for Aquarium: An Effective 2-Ounce Solution! by Raffaella Lopez

Follow the dosage instructions and you won't be disappointed. It's amazing to see how it works. Red smear on glass and gravel just goes away after a few days, but be realistic. If your tank is covered in slime, you should manually remove whatever you can before using it. Otherwise it takes several sessions and doesn't work as well. Be careful - this will overload your skimmer! I've found that a few drops is enough to get my skimmer going when the flow slows down or stops. (Actually, that alone is worth the price!) The liquid version is easy to use and gives you complete control over dosing.
