Marine Water LSS
As soon as the installation of a MARINE aquarium has been completed and filled with water, most people crave to see it become populated with some live creatures. This is potentially dangerous to the livestock as they can die easily. The water first needs to be conditioned as the chemical changes take place. The first stage of 25 – 30 days, no life is added to the tank. Hereafter, we add a few of the hardy selected fish species.
The reef aquarium will also go through various stages of alga development over a time period of approximately 3 - 400 days. This is completely normal. We are slowly stocking the tank as we go along as well!
Again, this process can be speeded up with the application of a Bacterial supplement that will allow the stocking of the aquarium within days of completion of installation.
Patience is most important during this break-in period of your new aquarium. Every aquarium follows its own rules and we work with these rules as closely as possible.
A. SEA WATER:
Seawater is available for the various uses from Hambani Aquatica in different Grades according to application. The different manufacturers of Sea Salt in its dry form have a range of nutrients and supplements contained in the salt mix, and these vary quite dramatically! Therefore, after we have done some lengthy testing of the different mixes in laboratory orientated conditions, we have now chosen the best mixes to offer you either as a dry mix or ready-to-use seawater.

B. WATER MOVEMENT AND FLOW:
It is well documented that the capacity of water to absorb oxygen drops as the temperature increases. Wave simulation pumps that can provide from 2000 litres per hour at the surface create a high oxygen exchange level between water and air. Above all, the metabolism of virtually all inhabitants is stimulated by flow, whereas oily algae are inhibited by flow.
C. FLOW PULSATION BY MEANS OF A POWER TIMER:
If one observes the movement of water in the sea, it consists essentially of two forms of motion: The wave motion near the surface and a flow which is caused by the influences of the moon, wind, heat and tides.
We now have a relatively simple electronic device with which the constant flow of pumps can be converted into pulses of adjustable power and duration to simulate the conditions in the open sea. Furthermore, in the tropics, winds and waves die down at night and the fish rest peacefully on the reef. To simulate this effect the controller switches off the pulses at night by means of a photo-electric cell, which senses the lights are off, allowing the pumps to operate on a constant reduced flow rate.
Experiments with these timers have shown that waves rather than steady current eliminate “dead spots” in the aquarium. Fish and invertebrates thrive on these simulations.
D. Life Support / Filtration Systems:
In modern aquaria filtration is of great importance. The beauty of an aquarium demands crystal clear water and an efficient filter system. However, in order to keep the inhabitants of the reef tank healthy, the invisible toxic substances must be decomposed as naturally and as far as possible. In Marine aquariums, there are a variety of applications for filtration that need to be applied. These variations depend entirely on the type of livestock you choose to keep, as the systems can vary according to this fact.
1. Mechanical filtration.
2. A bio-degrading filter designed as a biological percolating, or trickle reactor. The reactor establishes aerobic and anaerobic bacteria to decompose toxic substances and convert the matter to harmless substances.
3. Chemical Filtration.
4. Sand bed Filtration
5. Reactor Filtration.
6. Trickle Filtration.
E. PROTEIN SKIMMING:
In the ocean it is generally accepted that around 1000 litres to 10 000 litres of water are available to each fish. In an aquarium the stock levels can reach 50 times this. The waste matter in the aquarium produced through these stock levels consists of protein, cellulose, urea, and residues. Fortunately for the aquarist, these compounds are surface active, or surfactants.
This waste matter is made up of long molecules, one end of which is attracted to air, the other to water. A protein skimmer takes advantage of this situation by producing foam in the form of air bubbles around which the surface-active material can accumulate. It is then a simple matter to remove the waste that the skimmer collects in the tubular cup.
Protein skimming or foam fractionation is the process by which dissolved and particulate organic carbons are removed from a liquid, in this case the fish culture water, by adsorbing them onto the surface of fine bubbles rising in a closed contact column against a counter-current of water flow. The bubbles burst and form stable foam at the top of the water column and the accumulated organic wastes are discharged from the column along with the foam produced.
F. Calcium Reactor
A Calcium Reactor is a precision crafted reaction chamber for the accurate adjustment of calcium levels in the aquarium. Because Calcium Carbonate is not readily soluble in seawater at natural pH levels it is therefore necessary to temporarily lower the pH in the reaction chamber in order for the Calcium Carbonate to dissolve. This is achieved by carefully adding a controlled amount of Carbon Dioxide into the chamber and then recirculation of the contents. This results in a localized drop in the pH value and the creation of small amounts of Carbonic Acid and Calcium Bicarbonate. Controlling the levels of Calcium Bicarbonate produced is achieved through the use of a pH controller and electronic solenoid valve which controls the quantity of Carbon Dioxide added to the chamber.
G. THE OSMOREGULATOR (Replacing Evaporated Water):
In nature, a constant water supply ensures that the high losses of water caused by evaporation are equalized, and therefore a constant water composition over long periods. Where the osmotic conditions, i.e. the content of dissolved salts (ions) are the most balanced, we find the most varied plant and fish communities in nature. The osmolators are one part of the system with which you can keep the osmotic level of your aquarium constant at all times. At a rate of evaporation of only 2 to 5ml = 30 to 100 drops, the sensor switches on the electronic system and adds water from the storage container.
H. REVERSE OSMOSIS WATER:
Although our tap water is suitable for drinking, it is unsuitable for use in aquariums due to the quantities of dissolved minerals and chemicals in the water. By passing tap water through the reverse osmosis purifying unit which is made up with a 1-micron pre-filter, an activated carbon filter, the R/O membrane and an optional de-ionizing filter, chlorine, chloramines, nitrates, phosphates, heavy metals, pesticides and other toxic chemicals are removed. This water, 99,98% pure, is now ready for the replacement of evaporated water in the aquarium.
