## Overview

TL Reefs GFO Phosphate Remover uses granular ferric oxide to permanently bind phosphates in saltwater aquariums, preventing leaching and maintaining crystal-clear water. Ideal for use in fluidized reactors or high-flow sump areas, it ensures stable, low phosphate levels with easy dosing and monitoring for up to 50 gallons per ½ cup.

## Description

Granular Ferric Oxide is a popular means of reducing and maintaining low phosphate levels in your aquarium. There are many sources of phosphates in your aquarium. They can come from your base rock, fish food, or any other organic matter that enters the tank. GFO removes phosphate by molecular bond and will not leach them back into your water when exhausted. The most popular and effective implementation method is with the use of a fluidized reactor. Use a flowrate through the reactor just strong enough to keep it gently tumbling. This will help prevent clumping and channeling of your GFO media. The other method of use is by filling a media bag, and placing in a high flow area of your sump, or filter compartment.

## Features

- Permanently bonds phosphate and will not leach back into aquarium water
- Rinse before use. Use 1/2 cup per 50 gallons of aquarium water
- Monitor phosphate levels and replace when levels begin to rise

## Questions & Answers

**Q: Will this work in freshwater aquarium**
A: Yes, it will remove phosphate from freshwater.

**Q: How does this compare to the gfo from brs?**
A: Similar, looks the same. My Phosphates are at 0 so it is doing its job. I change it every three weeks so not sure about longevity, I think the BRS product only needs to be changed every 2 months, so that may be something to look into.

**Q: Can this be used in a fresh water tank with a sump?**
A: Yes, this will work in freshwater with a sump.  You will want to place the GFO in a mesh bag or media reactor, to keep it contained.

**Q: How often should you change the GFO out?**
A: Check your phosphate. When the phosphate goes up change it out. You want it to be low but not zero. You will get cyno blooms then.
