## Overview

TL Reefs GFO Phosphate Remover is a granular ferric oxide media engineered to permanently bind phosphates in saltwater aquariums. Ideal for use in fluidized reactors or fine mesh bags, it rapidly reduces phosphate levels that cause algae outbreaks, ensuring a healthier reef environment. Each 1lb pack treats up to 100 gallons and offers long-lasting, cost-effective phosphate control trusted by reef enthusiasts.

## Description

Product 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. They are a leading cause of algae problems, including diatoms, hair algae, and cyanobacteria. 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. Directions Rinse before use. Use 1/2 cup per 50 gallons of aquarium water. For best results, use in a fluidized reactor with a flowrate strong enough to keep the GFO gently tumbling, or place in a media bag in a high flow area of your sump or filter compartment.

Review: works FAST to reduce phosphates - I prefer to not use socks because of the amphipods and copepods in my large mixed reef saltwater system, which is probably why a pound of this powdered GFO lasts me almost 3 years. I'm back for more, but like everything else in the aquarium hobby the price has gone up since I first got this. However, this powdered GFO is still among the most affordable options for reducing phosphates. They say 'rinse, rinse, rinse' but I'm lazy. Because I'm using a bag to hold my GFO plus filter sock to hold the GFO bag, I let the filter sock 'rinse' but I enclose a photo as some of you may not like that super fine powder that escapes the bag to be running around in the sock... but I figure even that fine powder is reducing phosphates so I'm not wasting the extra fine powder most probably rinse away and I find it is kept contained by the sock. Also, to the guy who complained about his fine bag - compare his photo of bag to my photo of bag. A fine mesh bag designed to hold powdered filter media is going to appear like solid thin fabric so that other guy was doomed just by his choice of bag. Don't just go with any bag that says it is fine - actually LOOK at the bag to ensure it looks like what you need for fine granules. You'll find many more uses for this grade of mesh, so that is what I keep around for my various aquariums needs. I have media reactor that I use cubes coated with GFO but that is a more expensive option than this powdered GFO. When the cubes exhaust their phosphate absorption and/or my reactor gets gunky, I usually am living life too busy and I have a mess on my hands I have to get under control asap so death doesn't keep rolling through my corals from too high phosphates. I like this option because it is easy and results are immediate. I use a very fine mesh bag and I just pour in this GFO. Then I put the mesh bag filled with GFO into one of my two filter socks (dual overflow system) that are in the first chamber of my sump. This forces more water thru the GFO in the fine mesh bag than if the fine mesh bag were just laying on the bottom of my sump or even if I tried stuffing the bag between sump section baffles, as water wants to take the path of least resistance which is going around my fine mesh bag stuffed with GFO. When my socks get dirty, I throw those in a bucket and collect a bunch before I deal with the sump dirty socks. I put new socks in place and just move the GFO from the dirty to clean sock, as the GFO is still in its fine mesh bag I tied shut. If you use socks or if you have a media reactor designed for powders, this powdered GFO is absolutely the easiest and most affordable way to reduce phosphates.
Review: Works - Really dusty and extra small grain sizes. Make sure you have a really fine mesh bag or reactor. Works quickly.

### ⭐⭐⭐⭐⭐ Great GFO!
*by B***S on 10 December 2019*

I'm not sure what all these other reviews are talking about with the high dust. I rinsed mine pretty well and it did have a little more dust once turned on, but my tank cleared up. I have the reactor infront of the skimmer so that it catches any by product released from the reactor. All depends on your filtration if you ask me. NOW, this product works! My phosphates were at .16 ppm and this GFO reduced them to .04 ppm after one day! This product works. Just know how to use it. Rinse it, rinse it again, and rinse some more. Then add to the media reactor, you don't need much. If you jam pack the reactor then it will clump and sludge. I didn't even use the recommended amount from the bad directions, I used less and it still worked! You want the media to gently tumble in the reactor and not going too crazy. If you know how to use it, then it will yield great results.
