Alkalinity is of extreme importance in a marine aquarium, owing to the manner in which it influences pH. In an aquarium, weak acids formed by oxygen respiration and the decomposition of organic material gradually deplete alkalinity. If left unchecked, the alkalinity drops below a critical level and pH begins to fluctuate more wildly than is normally suggested (a daily pH shift of +\/-0.2 is normal in marine aquaria), causing stress to livestock. Alkalinity is also depleted by reef-building organisms during the production of aragonite (~60% carbonates by weight), and is therefore very important for their rapid growth.\u003cbr\u003e\r\n\tMaintaining the alkalinity in marine aquaria between 7 - 12 dKH (2.5 - 4.3 meq\/L) will generally maintain pH within the desired range. The rate at which alkalinity is depleted in a reef aquarium is determined by the stocking density of reef-building livestock, type of lighting, rate of water circulation, and other biological, physical, and chemical conditions; therefore, each aquarium will have different requirements for the rate of alkalinity supplementation. Once the rate of alkalinity depletion in the aquarium has been determined, the proper dosing rate of this product can be easily calculated. It is recommended that a quality salt mix with the proper (not augmented) alkalinity and concentrations of major, minor, and trace elements be used to establish natural seawater parameters in the reef aquarium, providing a stable ionic foundation on which to build.

Add product at the maximum rate of 5 ml (1 capful) per 30 US-gallons daily until the desired alkalinity is attained, then dose daily or weekly as needed (see below) to maintain alkalinity between 7 - 12 dKH. When used in this fashion, 250 ml treats up to 1,500 US-gallons (5,678 L).\u003cbr\u003e\r\n\tAdvanced: Determine the alkalinity in the aquarium using an accurate test kit before supplementing. Shake product well before using. Each ml of Brightwell Aquatics ALKALIN8.3 will increase the alkalinity in 1 US-gallon (3.785 L) of water by 3.1 dKH (1.1 meq\/L). If the initial alkalinity in the aquarium is below 7 dKH (2.5 meq\/L), add this product at the maximum rate of 5 ml per 10 US-gallons daily until the desired alkalinity is attained, then dose daily or weekly as needed (see below). For minor adjustments to alkalinity, add 5 ml (1 tsp) of Alkalin8.3 per 30 US-gallons of aquarium water as needed to maintain the alkalinity within the proper range. Always try to maintain the alkalinity within a range of +\/-1 dKH. To determine the rate of alkalinity depletion once the desired alkalinity has been acquired, measure the alkalinity at the same time each day over a one- to two-week period. To determine the daily dosing rate (preferable to weekly dosing) for alkalinity maintenance: estimate the volume of water in the entire aquarium system; divide the daily decrease in alkalinity by 3.1 (when measuring alkalinity by dKH; divide by 1.1 when measuring by meq\/L); multiply this number by the volume of water in the system to get the daily dosage required (ml) to maintain a stable alkalinity. Daily dosing maintains a more stable alkalinity and pH (and a more natural environment) than dosing weekly, in which the alkalinity spikes just after dosing and then gradually decreases throughout the course of the week.\u003cbr\u003e\r\n\tNote: If pH does not reach desired level when using this product as directed, such as when gas exchange in the aquarium is insufficient, addition of a pH-increasing product (i.e. Brightwell Aquatics PH+) may be required.

Once the balance between calcium and magnesium has been established, subsequent calcium supplementation yields immediate positive results.

These organic particles typically become colonized by various microorganisms (primarily bacteria and protozoans) during their descent towards the sea floor; the decomposition of the organic material by the microorganism colony\" on each particle recycles the nutrients locked up within it. The constant descent of these particles through the water column has the appearance of snow fall, hence the name marine snow\". While marine snow is primarily associated with productive regions of the open ocean rather than tropical coral reefs, the concept (with some improvements adressing the requirements of reef-building organisms) may be applied to reef aquaria as a means of simultaneously delivering organic and inorganic nutrients to corals and other suspension-feeding invertebrates.\u003cbr\u003e\r\n\tBrightwell Aquatics Reef Snow effectively replicates the concept of marine snow by combining a core substrate\" of carbonate-bound, non-conservative major, minor, and trace elements (all in aragonite ratios) with marine-derived proteins and fatty acids (all in coral tissue ratios). It does not contain any sugars or their derivatives. Reef Snow delivers both organic and inorganic nutrients to corals and their allies, clams, tube worms, and other suspension-feeding marine invertebrates; it may be of particular benefit to the hobbyist wishing to maintain azooxanthellate soft corals in deep-water biotope aquaria. The collective benefits of providing these nutrients in the same package\" are increased growth rates of both soft tissue and skeletal material.\u003cbr\u003e\r\n\tReef Snow does not require refrigeration, however storage in a cool, shaded area will prolong the shelf-life.

Turn protein skimmer and other forms of mechanical filtration off prior to adding Reef Snow to aquaria, and allow 10 - 15 minutes after use before resuming operation of filtration. Most zooxanthellate corals extend their tentacles at night, when the majority of coralivorous and zooplanktivorous fishes are asleep and the abundance of zooplankton in the water column passing over and through the reef is at its greatest. Therefore, the most sensible time to feed Reef Snow to corals is after all lights in the aquarium have been off (preferably for at least one- to two-hours) and the room is dark. Using a dim flashlight, illuminate the area immediately upstream of the coral to be fed, then feed as directed below. Slight cloudiness of the aquarium water accompanying dosage of Reef Snow is a result of the inorganic active components entering solution and will dissipate rapidly.\u003cbr\u003e\r\n\t\u003cb\u003eTarget Feeding (recommended): \u003c\/b\u003e\u003cbr\u003e\r\n\tTarget feeding may be carried out with a lengthy piece of rigid air tubing, plastic syringe, pipette, dropper, or similar device; suck a portion of Reef Snow into the feeding device, then slowly discharge the contents of the device 2 - 4\" upstream of the target organism(s).

Calcium hydroxide is used to prepare limewater (kalkwasser)  solutions that will maintain calcium concentrations at natural seawater levels.  Kalkwasser solutions maintain calcium directly and carbonate alkalinity  indirectly. However, its capacity to perform these functions is dependent on  evaporation rate and CO2 concentration. If these two factors are insufficient  you can provide additional calcium with Reef Advantage Calcium\", Reef Complete\",  or Reef Calcium\", and carbonate alkalinity with Reef Builder\" or Reef Carbonate\"  (do not mix these directly with a kalkwasser solution).\u003cbr\u003e \u003cbr\u003e Many who use kalkwasser are quite successful with their marine systems and find  it to be an effective way of maintaining calcium. However, it can be a difficult  technique for the beginner to master. The carbonate alkalinity must be monitored  and adjusted to ensure that it does not become depleted through chalk (calcium  carbonate) precipitation. The magnesium concentration must also be monitored and  maintained since precipitation of magnesium hydroxide (arising from excess  hydroxyl ions) can lead to a change in the balance of the various buffer systems  present which can result in drastic pH shifts. Additionally, magnesium is an  essential component of seawater that is required by all corals. There will be an  increase in the build up of chalk on substrate and plumbing surfaces which will  require more frequent cleanings in order to maintain the proper functioning of  the aquarium. If due care and diligence is paid to all of these factors, there  is no reason one cannot maintain a successful reef system while using kalkwasser.  While Reef Kalkwasser\" is a high purity and economical limewater mix, the  beginner, or someone with not as much time to devote to their system, may prefer  to use other less involved methods for maintaining proper ionic concentration  levels.\u003cbr\u003e \u003cbr\u003e Directions\u003cbr\u003e Never add this product directly to the tank.

Drip this  solution into tank. Monitor pH and carbonate alkalinity. Adjust rate of addition  to maintain a stable pH (8.3—8.4). HINTS: Adding 4 L (1 gallon*) of a saturated  kalkwasser solution to 150 L (40 gallons*) will raise calcium by 24 mg\/L.

The most frequent  causes of magnesium deficiency are use of kalkwasser, frequent overdosing of a  carbonate additive, or low levels in the salt mix itself. Kalkwasser, for  instance, precipitates magnesium as magnesium hydroxide while excess carbonates  precipitate it as magnesium carbonate. In both cases, this means that magnesium  that was present in the water is now unavailable. Of the two, magnesium  hydroxide and magnesium carbonate, the former is more problematic; it is  extremely insoluble. Once magnesium has precipitated as magnesium hydroxide, it  will never redissolve. Magnesium carbonate will redissolve; however, it does so  slowly.

Use the following formula to  determine how much to add to your top-off water: g=vm\/80 (g=grams to add to top  off water, v=volume of tank in liters, m=amount to raise magnesium in mg\/L). For  example, if you want to raise magnesium by 10 mg\/L in a 200 liter tank, then you  would add (200x10)\/80=25 g into the top-off water. [For reference: 1 gallon*=3.8  liters, 5 g=1 teaspoon*].
