III. Phosphate Removers:
Phosphate being the building block of many organic compounds; is present in higher levels within
some Carbonate media, specially with crushed gastropod shells. This is one of the underlying
reasons as why Vertex™ only recommends coral skeleton (Coarse Media) instead of the
conventional smaller particle size media. Further to that it is imperative to acquire your absorber
from a reputable source that guarantees purity and cleanliness of the material.
To reduce the phosphate concentration of your effluent; it is possible to use phosphate absorbers
in your TOP secondary chamber's Sub-chamber. Ensure that you are using proper media that will
not react with saltwater of lower PH range in a negative way. While the input saltwater can have
PH as high as 9; the effluent PH can drop to lower than 6, specially if the reactor is not dialed in
properly. In most cases Iron-Based absorbers are not suitable.
Tip: Always rinse your media with RO water prior to use. While not always necessary, it is best to soak
your media in RO water overnight. Doing so will reduce the chance of introducing any contaminants
to your system.
Carbon Dioxide:
B)
As mentioned previously, Carbon Dioxide is required to dissolve the Calcium Carbonate Media.
Due to the fact that C02 is supplied in a pressurized container; it is imperative that you observe and follow
all safety precautions to allow presence of such equipment in your living, commercial... space.
Only use ¼" CO2-Safe tubing. Respect and follow local, state and Federal rules and guideline as how CO2
tanks and equipment must be handled, used, stored and/ or operated.
1- Connect your CO2 supply to the bubble counter. ( CO2-Safe tubing not Supplied)
2- Use CO2-safe tubing to deliver CO2 from the bubble counter to the reactor manifold.
Warning:
 CO2 tanks may leak if improperly stored or handled. Carbon dioxide cannot be detected by the
human senses, as it has no taste, odor or visible appearance. Carbon dioxide replaces oxygen in
air, meaning that as a room fills with carbon dioxide, the air becomes less and less breathable.
Eventually, an undetected carbon dioxide leak can cause suffocation and death.
 Another potentially dangerous situation is an overfilled tank. An overly full tank poses a serious
risk to anyone in the area. Depending on the tank size, its safety valve is designed to only handle
a certain amount of gas. When pressure exceeds the valve's capacity, the valve will burst, causing
a leak and potentially injuring anyone nearby with shrapnel. Refill your CO2 bottle only at an
authorized dealer. The CO2 canister must be checked during each refill to ensure there is no loss
of structural integrity and/ or possible leak that can result in explosion.
