Seachem

SeaChem PhosGuard is a high capacity and high efficiency filtration product for removing phosphates and silicates from marine or fresh water aquaria. Unlike competing products, PhosGuard is bead-shaped for optimum flow characteristics and has an exceptional porosity for enhanced capacity. PhosGuard has a working capacity to remove 20 to 60 mg/L phosphate in 100 gallons with a similar impact on silicates. It may be used continuously or intermittently, and will not release removed phosphate. PhosGuard will cause a decline in hair algae and enhance coral growth. Each liter treats up to 300 gallons. Marine or freshwater use.

A great product

So tired of reading the marine blogs on what they don't know(a lot)? All they say is how this leaches back into the tank when exhausted. According to seachem on the label and at their site it does not. This is easier for me to use than gfo. It has less friction and does not clog up in large use or require a big pump to push the water through. Rinses quicker also. I put almost a 4 liter amount in an 4l reactor and no ill effects from any corals or inverts, anything in my 180 reef. Very cost effective to me.

gets rid of unwanted algae

I love this stuff. I used to stress out over nuisance algae showing up on my rock when my nitrates and phosphates read zero on my salifert test kits. Now whenever the algae starts to show up, I replace the stocking full of phosguard with a fresh one. Within a few days, any exposed rock in my tank looks super clean without a trace of algae. It must be removing unreadable phosphate levels I'm guessing. Whatever the mechanism, it breaks my algae cycle and eliminates it.

Works Great

I've used this product for a while now and have had great results with it. This is used in the same way as many others and in my opinion works just as well as some of the more expensive ones giving you the same results. My phosphates are zero and being able to buy it in a larger quantity makes it even better.

Works!

Made a huge impact on my algae after 1 day. The hair type stuff on the back wall started turing grey. I did about 1/3 the recommended dosage to start.
