Brightwell Phosphat-E Liquid Phosphate Remover, 250ml
The Brightwell Phosphat-E Liquid Phosphate Remover is a powerful solution designed to rapidly reduce reactive phosphate levels in aquariums. It begins working immediately upon addition and helps maintain a safe environment for reef and marine fish-only setups.
Each 1 ml of the product can remove 1 ppm of phosphate from 4 US-gallons of water. A single 250 ml bottle can treat up to 1,000 US-gallons of water, making it highly efficient for large or heavily stocked tanks.
It performs especially well in systems with high dissolved organic material and supports long-term phosphate control. The formula is over 50% stronger than many competing products and developed by a marine science specialist.

Used this in a 100-gallon reef tank with high organic load. After one application, phosphate levels dropped significantly. It works fast and doesn’t cause any fish stress. Will use it regularly for maintenance.
Sally Clarkson –
Good results in a heavily stocked tank. Took a few days to see full effect, but phosphate levels stabilized. The bottle lasts a long time and is easy to dose.
Harry Bond –
This product outperformed others I’ve tried. After just one use, my phosphate readings dropped from 2.5 to 0.8 ppm. Works well in a 50-gallon marine tank with live rock.
