Phosguard by Seachem is a product that effectively removes phosphates and silicates from both freshwater or saltwater. It comes in the shape of tiny spherical pellets, thus having an increased surface area with hydrodynamics to uptake any unwanted phosphate molecules within your aquarium’s water column.

For the best results, you should rinse your product before first use and let aquarium water flow through it. The location of placement matters as well– place them in such a way that increases surface area for greater dissolution rates!

To make the PhosGuard easier to maintain, you can use a filter bag. Place it in there and then place where water flows so that its contact with dirt is minimized while still being effective!

Seachem’s PhosGuard is a quick-acting, one way absorbent that eliminates phosphate from water. Unlike an exchange resin which releases negative ions into the solution and thus requires media bags or canister filters to work efficiently; this product needs no additional equipment since it acts like an excellent filtering agent without releasing contaminants in return for its service.

Phosphate levels in drinking water can be a serious threat to invertebrate life. To prevent this, use PhosGuard when you have plenty of time and patience for its effective treatment – 85 mL (1/3 cup) per 400 L or 100 US gallons will remove up most harmful phosphates found naturally within lakes, rivers or streams without overdosing on phosphate measures that could stress out your aquatic friends.

Pros of Phosguard by Seachem

The filter media is durable and effective against phosphates. It can use until exhausted without any additional steps, making it a great option for aquarium filters that need to last longer than the average.

Cons of Phosguard by Seachem

Seachem’s PhosGuard is a high-end product that costs more than other aquarium supplements on the market. This could make it difficult for some people to afford, but its benefits make up for this price difference and may be worth investing in if your tank requires frequent maintenance or you have costly fish like Goldfish!

PhosBan is a great way to create an environmentally safe phosphate removal system. Unlike all other products on the market, which use toxic metal hydroxides or organic solvents like glycerol and butanol as their adsorptive agent in solution; this one uses nothing more than some simple synthetic ferric oxide granules mixed together with water!

This high capacity product has been proven effective at removing even very large quantities of stubborn contaminants from both saltwater (with its naturally occurring mix) AND freshwater fish tanks without causing any long term damage whatsoever- proving just how versatile it really can be made for your needs.

Pros of Two Little Fishies Phosban

Two Little Fishies Phosban is a natural, phosphate removing compound that has been shown to be effective for up to several months. It can even remove the build-up from swimming pools!

Cons of Two Little Fishies Phosban

One of the main reasons for this product’s lack-luster performance in media bags is that it does not mix well with other chemicals.

Buyer’s Guide: Why Should You Remove Phosphate?

The phosphorus in aquariums tends to be less of a problem than it would be outside the water. Some people worry about phosphate, but most aquatic organisms use it just fine and with no ill effects on their health or lifecycle as long you check for compatibility before adding any new animals into your tank!

Without enough maintenance, when phosphate levels rise exponentially and algae proliferates fast. Such overgrowth of a bloom can cause the tank’s oxygen to deplete which would harm your underwater plants as well as fish in it.

If there is not enough oxygen in the water for your fish, they will eventually die. Algae are responsible for suffocating them as it blocks out most of their breaths and leaves less space between themselves than what’s needed to inhale properly.

A phosphate level of 0.5 ppm or lower is a good benchmark, but levels higher than this can be harmful to the life in your drinking water.

How Does Water Acquire Phosphate?

Even tap water can cause problems. It’s not just a matter of where you live, but also how well your source is maintained and treated with chemicals to keep it clean before delivering any kind or drinkable H2O in order to prevent corrosion from happening which leads phosphate being added back into the potable supply as another essential element necessary for plant life!

One way to test if your tap water contains phosphate is with a water conditioner. You can also try testing for it by using grocery store fish food as an additional potential source of phosphates in the sample, which may result from preservatives added during processing or preparation.

There is a chance that your carbon filters might release excess phosphate into the water. However, many modern filers are designed to prevent this from happening so you might not know about it!

How To Maintain Low Levels Of Phosphate In Water?

  • One way to cut back on phosphate production in your tank is by cutting down the amount of food you feed, and when. A fish can survive with just a pinch per day which isn’t much for an adult sized one like most betta species are. The best thing would be if they refused any offered items so as long as their water stays clean there’s no need worry about problems arising!
  • To avoid high levels of phosphate, choose brands of fish food that have lower phosphorus. High concentrations can be harmful for pets and people alike as it will lead to an unnatural looking white coating on the tongue or other organs (such has kidneys), which could cause permanent organ damage over time if not addressed quickly enough by a vet professional with experience in this area!
  • All tap water contains a level of 1 ppm phosphate, which should not be ignored. If your aquarium’s total phosphorus levels are too high and the sum is greater than 4 mg/L in this typeZeroBachsiverng source – meaning that you may have an issue with algae growth or poor circulation due to its accumulation on plants within the tank- then consider using bottled mineral waters instead for better results!
  • To reduce the amount of phosphate in your tank, change about 10-15% each week. This will help to keep unwanted compounds from building up and drowning out other beneficial bacteria!
  • A clean tank will help to keep nitrates down, so it’s important that you vacuum the floor and get rid of organic decay material such as uneaten food for your fish.
  • If you want your fish to live a happy life in their tank, make sure that the carbon filter is treated or has been designed not release phosphates into it.
  • Avoid using water treatment unless necessary. When you add chemicals to alter pH or change its hardness, they can contain phosphate compounds that are harmful for the environment and our health!
  • Be careful while choosing your product because these treatments have negative impacts on both man-made structures such as buildings in cities and natural resources found deep underground like aquifers – so choose wisely!.

Mechanism of Action

When looking at phosphate remover products, they will either be a liquid additive, a sponge or resin, or a granular ferric oxide. All of these products are effective at sequestering away phosphates but will act very differently within your environment.

Liquid additives are probably the most common type of phosphate remover. They are a concentrated liquid that is added to your aquarium water. This liquid will bind to any phosphate in the water and remove it. The downside to liquid additives is that they can be difficult to dose properly, and can also be harmful to your fish and plants if not used correctly.

Sponge and resin products are also common phosphate removers. These work by attaching to any phosphate in the water and removing it. However, unlike liquid additives, these products are not harmful to your fish or plants. The downside to these products is that they can be less effective than liquid additives and can also take longer to work.

Granular ferric oxide is a less common type of phosphate remover. It works by sequestering the phosphate in a solid form. This makes it easier to remove and prevents it from being re-released back into the water. The downside to this product is that it can be more expensive than other types of phosphate removers.

Where to Put it in Your Tank

GFO (granular ferric oxide) and sponge filters are two popular methods of removing phosphates from an aquarium. Both have their own benefits and drawbacks, and where you place them in your tank can have a significant impact on how well they work.

GFO is a powdered form of iron that removes phosphates from the water. It needs to be placed in an area of high water flow, often within a filter component, for best results. If it’s not placed in a high-flow area, the GFO can become clogged and stop working.

Sponge filters are a type of filter that uses a sponge to trap debris and organic material. They can also be used to remove phosphates from the water. Like GFO, they need to be placed in an area of high water flow for the best results. If they’re not placed in a high-flow area, the sponge can become clogged and stop working.

Both GFOs and sponges can be messy, so placing them in a mesh bag is frequently recommended. This will help keep them from clogging up the filter and making a mess.


Phosphates are found in tap water and food so it is best to use one that works for fresh or saltwater tanks as well as those with fish or invertebrates. They work by binding phosphates from the tank’s substrate and filter media which prevents them from being dissolved into the water column where they feed unwanted algae growths.

Frequently Asked Questions

Will carbon filter remove phosphates?

70-90% of the phosphate you take in with your tap water is removed by high quality charcoal filters.

How much phosphate does PhosGuard remove?

PhosGuard is a phosphate removal system that can remove up to 60 mg/L of phosphates with no other metals or chemicals in it. It’s proven as an effective way for treating drinking water, and has been around since 2000!

How long does phosphate remover take to work?

Will have results in 24 hours.

What causes phosphate in fish tanks?

Phosphates are the natural byproduct of waste breakdown, including uneaten food and fish excrement. If you allow these phosphorous compounds to build up in your tank they can contribute towards algae blooms which will starve oxygen levels for both plants as well as creatures that live there like betta fry or other small aquarium animals.

Does PhosGuard affect pH?

The PhosGuard does not directly alter alkalinity levels. However, you may notice an indirect connection between adding more of this product and increasing the KH with time- as it works to naturally restore natural pH balance in your aquarium setting over many months or years!
