FAQ & Support

Question One
What is the size of the aquarium that I should purchase?

Choosing the size of an aquarium depends on several factors. Your main considerations should be: the space available, budget, and type of reef system you desire.


Depending on the space available and budget, we will propose a system to match your needs. A reef aquarium consisting large number of fishes will also mean you need a bigger aquarium to house the fishes.



Question Two
How many different shapes are available for the tank design?

Glaswerkz offers many different shapes and sizes for reef aquariums. Besides the popular rectangular shaped design, different shapes such as triangular, hexagonal and octagonal aquariums are also available.


Whatever shape and design you choose, you can be sure Glaswerkz will design the reef system to function optimally.



Question Three
Why does setting-up take so long? Why can’t the entire system be set up within a day?

To achieve a healthy reef aquarium, it is essential to understand the NITROGEN cycle.


Ammonia are constantly being introduced into the reef aquarium via fish waste and uneaten food. Ammonia, even at small quantity, are extremely harmful to fishes and corals. In a healthy reef aquarium with proper biological filtration, Ammonia will be broken down by aerobic bacteria into Nitrite, and subsequently broken down further into Nitrates. Anaerobic bacteria will then break down Nitrates into Nitrogen gas, which are harmless to fishes and corals.


With this understanding of the NITROGEN cycle, it is clear that the introduction of fishes and corals into reef aquarium is only safe after the biological filtration is effectively functioning. This is the reason why stocking the entire reef aquarium within a day is never encouraged by Glaswerkz.



Question Four
What is the nitrogen cycle?

It is a dynamic progress that goes on in your aquarium 365 days year. There are three stages of the nitrogen cycle: First stage is when fish are introduced to aquarium and urine, faeces and any uneaten food is broken down into ammonia. Ammonia levels usually start escalating on the third day after the introduction of fish. Second Stage – By this stage the ammonia levels should have dropped dramatically, however nitrate levels can be dangerous to some fish. Nitrate on most accasions begin to rise by the end of the first week after fish are introduced. Third Stage – In the last stage of the nitrogen cycle nitro bacteria converts into nitrates. Nitrates are not harmful to fish in low temperatures. Partial water changes can regulate water to a safe range.



Question Five
Does the aquarium require a lot of care?

We supply our aquariums with simple but sophisticated filtration equipment, which effectively look after the water for you. The aquarium glass will need cleaning from time to time to remove algae growth and we recommend that 10 to 20% of the water is changed approximately every couple of months. We also offer an optional maintenance service so that you never have to get your hand wet, please contact us for more details.



Question Six
