If you want to keep fish, aquatic plants or coral reefs in your aquarium, then there are several things you need to be aware of. To maintain the growth and health of its inhabitants, you need several components and need to check the circulation of certain elements like phosphate. Rowaphos is a chemical that removes phosphate from tank water.

Things like substrate, lighting fixture, filtration system, heater are necessary to keep your aquarium in shape. The water in the aquarium has to be kept clean and fresh at all times.

But it is easier said than done. This is because the water attracts a lot of pollutants such as algae growth, uneaten particles, fish waste, and other kinds of microorganisms that can easily contaminate the tank water.

All these pollutants can make the fish sick and also turn the aquarium into a mess. For this reason, you need filters and pumps to get rid of the toxic materials from your aquarium effectively.

However, your filtration system might not be able to remove the pollutants properly. So you need a media reactor, also known as a phosphate reactor.

Rowaphos is an enhanced type of chemical filtration system which is applicable for both saltwater and freshwater tanks. A high level of phosphate in the tank water can cause algae bloom and other significant problems for the fish and aquatic plants.

In this Rowaphos review, we will focus on its different features and benefits as well as the pros and cons. Based on the provided information, you can decide whether or not to purchase this product.

Things to Consider Before Buying


A phosphate remover can be used as a supplement in the filtration system. Most of the time, you do not need a phosphate remover if your regular filter is doing its job efficiently.

It mostly depends on the size and contents of your tank. If you have a large aquarium, then having a phosphate remover is a good investment. In actuality, phosphates are present in every fish tank.

But they have to kept at the desired level to not cause an algae growth or harmful effects to the inhabitants. High levels of phosphate in the tank water can cause magnesium and calcium to decrease.

They are essential nutrients that act as fertilizers, and a drop in their levels can lead to harmful incidents.

  • Needs A Media Reactor for Higher Efficiency

You can use this phosphate remover in two different ways. It can be installed at the end of your primary filter system and can act as a final step after the mechanical and biological filters.

It can either be kept in the filter net that comes with the pack or installed amidst two layers of filter wool of the incoming and outgoing channel. Another way to use this substance is to put it in a canister filter, or in a media reactor.

You can keep the media inside the reactor if you want higher efficiency. Although it can be used with a standard filter system, using a single reactor for this remover can provide more benefits.

If you want a phosphate remover that works efficiently in your conventional filtration system, then we recommend the Fluval Clearmax Phosphate Remover. It can be placed directly in the aquarium or inside the filter system.
