THE CARBONATE HARDNESS IN SALTWATER – PART 2

Increasing the carbonate hardness of the aquarium The few lucky aquarists that have tap water free of harmful substances but rich in carbonates simply add those by replacing daily the water that evaporates. This operation, when possible, is only sufficient if there are only a few species that consume the calcium in the tank. In […]

ACTIVATED CARBON FOR MARINE AQUARIUMS – Part 3

What is the correct use of activated carbon? (Part 2) 4 Elimination of yellowing and medicinal substances The most common use of activated carbon is for the elimination of undesired substances from the aquarium’s water.

THE CARBONATE HARDNESS IN SALTWATER – PART 1

The carbonate hardness (abbreviation KH) is one of the most important parameters in a marine aquarium. The aquarist should regularly measure this value, because in a well-functioning biotope marine, the need for carbonates is enormous. The carbonate hardness can decrease by 5-10 ° in a matter of only days. What is the carbonate hardness? The […]

THE PH VALUE IN MARINE AQUARIUM

The pH value tells us about acidic and alkaline processes that take place in liquids. It is a very important information for the keeping of an aquarium, as variations in this value can bring drastic changes to the environment of our animals. Acidic substances reduce the pH value and alkaline ones increase it. Measuring is […]

ACTIVATED CARBON FOR MARINE AQUARIUMS – Part 2

What is the correct use of activated carbon? 1 Elimination of oxidising substances from the water The elimination of oxidising substances does not concern the above mentioned ability to absorb carbon, but instead it involves a different property: chemical absorption. In this process the substances that are able to oxidise, such as chlorine and ozone, […]

Measuring pH values in the marine aquarium

To determine the environmental conditions of an aquarium, we need a reliable pH measurement. This should also be performed regularly, for example once a week. It is appropriate to carry out the measurement always at the same time of day, to be able to really see the normal pH variations that take place during the […]

ACTIVATED CARBON FOR MARINE AQUARIUMS – Part 1

Activated carbon is a filter material, that has already been used in aquariology for a long time. As much as this material is well known, its correct use and the effects of using it to treat aquarium water are very unclear. The difference in quality between various types is so crucial that every aquarist should […]

The transport of coral fishes

Transporting coral fish is not always trouble free. If a single fish is moved while in a large tank of water, which is also filled with oxygen, as is usually practiced in specialized aquariological trade, then the entire move should be trouble free. But as soon as you want to transport a larger amount of […]

“DOPING” FOR WEAKENED TRIDACNA

The big mollusks of the Tridacnidae family can be weakened by transport and by incorrect care. Changes in the lighting and other environmental factors can have a negative impact on these animals, making them weaker. Normally, the symbiotic algae produce energy in the form of glucose, which is necessary for the animal’s tissues. If this […]

ORNAMENTAL ROCKS IN REEF AQUARIUMS – Part 1

Marine aquariums always contain large quantities of ornamental rocks. What is the reason for it? Are the rocks only used for aesthetic purposes, or do they also have biological value? Because of the often high cost of a living rock environment, many beginners or aquariofiles who wish to change from freshwater to marine wonder if […]

ALGAE INFILTRATION IN SILICONE

Black silicone has been for a long time considered highly effective, because it prevents the aquarium’s lighting from filtering out. The common opinion was that because of that, the growth of algae between silicone and glass would be inhibited. But it has been proved that for some types of algae what little light gets reflected […]

CALCIUM HYDROXIDE AGAINST HYDROID POLYPS

Hydroid polyps of the Myrionema genus sometimes develop so abundantly that they can constitute a problem, especially in hard coral aquariums. Some fishkeepers advise to eliminate the polyps by using calcium hydroxide powder mixed with water. First you stop the water circulation, and then you cover the polyps with the whitish solution. After a brief […]

Water replacement – How does it work?

It seems pretty trivial: water is poured in the aquarium. Sometimes, though, things can be a little more complicated than what can be assumed at first sight, since tap water contains calcium, carbonates, nitrates, phosphates and often many other substances, meanwhile only pure H2O evaporates from our aquarium. The water composition is, depending on geographical […]

Living sponges as filters for the reef aquarium – Part 2

Which are the most suitable sponges? Those aquariophiles who have already tried to keep in their tanks those bigger sized sponges available on the market, often have the impression that these organisms may represent an almost unsustainable animal group. For many sponges this can effectively be true, particularly if, during yield, transport and maintenance, they […]

Living sponges as filters for the reef aquarium – Part 1

An aquarium keeper who intensely deals with the internal structure and physiology of sponges, will presumably be surprised. With a relative and quite big probability, indeed, he will find out that living sponges, in their functionality, are surprisingly similar to those devices developed during the last few years in aquariology for water cleaning treatments. As […]
