The phosphate reactor you purchased can be used before your RO DI system or can also be used to filter the water out of your aquarium utilizing a sump (Maxi Jet 1200), through the reactor, and into a reservoir to be pumped back into your aquarium thus eliminating the phosphates that cause algae growth.
Which GFO should I buy?
High Capacity Granular.
Algae needs three main nutrients to grow: Phosphates, Nitrates and light. Reducing any one of these will significantly slow down algae growth, but rarely cause it to completely die off.
Once algae takes hold, it can be extremely difficult to remove. The best offense against algae is to take preventative measures and attack before an outbreak is apparent. Use the following suggestions and be aggressive if an algae problem is already present:
Good habits like these will aid in solving current algae issues as well as help you prevent an outbreak.
HOW OFTEN SHOULD I CHANGE GFO
You ought to change out the GFO once it is full and no longer able to remove any more phosphate. It is going to vary drastically from person to person. It is strictly contingent on the live stock you have, how often you feed, what you feed, how much you feed at a time, what your water change schedule is like, etc. It is very possible for one person to add ten times as much phosphate than another.
It is recommended that you start with changing every other month and adjusting accordingly. If you find that this isn’t keeping up with the amount of phosphate you are adding to the tank, then you should change it at a greater frequency. If you feel like you are a particularly heavy feeder, or use foods that you know are high in phosphate, then you should start by changing monthly.
Absolutely not. The GFO is harder that the carbon and will grind it to dust if you allow the particles to grind against each other 24/7. There is also no benefit to the tumbling if used with carbon. The tumbling is to prevent the GFO particles from attaching to each other and forming one giant rust ball. There is no need for this if the partials are not touching each other because of the carbon.
Slower the better. The slow tumbling action stops the particles from attaching to each other and forming one big rust ball. However the tumbling action also grinds the particles against each other and creates dust. So you want to set it as low as possible to prevent them from solidifying and at the same time minimize the abrasion between the particles.
A typical wet GFO weighs 75 pounds per cubic foot and our Standard dry GFO weighs 29 pounds a cubic foot. Both have essentially the same phosphate removing capacity on a volume basis, thus it requires 2.6 times as much wet GFO to treat an equivalent amount of water.
5.How does wet GFO differ from dry GFO ? (GFH vs GFO)
There are two main granular iron based medias. Granular ferric Hydroxide (GFH) is a wet product and Granular Ferric Oxide (GFO) is a dry product.
The products are extremely similar and in an aquarium environment there is going to be very little difference worth noting. Price and capacity should the primary motivating factors when purchasing for your aquarium.
The following is information provided by our supplier and relates to these products main application .
GFO/GFH is primarily used in the municipal water supply world as a tool to remove arsenic. The following are the benefits they feel their dry product has over the competitions wet product (GFH).
1) GFH is very heavy because of the water weight and costs more to ship. This results in the client paying nearly 50% more in freight costs.
2) GFO granules are physically more robust and less prone to physical attrition/loss.
3) GFH shelf life is considerably shorter because being wet; it is prone to decomposition and loss of surface area. Metal oxides produced and stored as wet products are gelatinous and prone to decomposition.
4) GFH can freeze in cold climates and mold in hot climates, GFO does not have either of these issues.
5) GFO is a crystalline form of iron oxide whereas GFH is mainly an amorphous form of iron oxide. The crystalline product has more consistency in terms of adsorption capacity and shelf li
