Review: Opened and half empty - It came opened and half empty !? How is this possible!?
Review: Size may be an issue. Make sure you have enough storage space under your tank. - The excel product works well and seems to be keeping the blackbeard algae at bay. I’ve been dosing at a higher rate so the 4L option made sense, given the price of the 250ml & 500ml options.
