Brightwell Aquatics Alkalin 8.3
$ 5.99
Highly-effective alkalinity(KH)-increasing (Buffer) solution.
- Helps increase pH stability in an aquarium by raising the alkalinity.
- Provides a source of carbonates, which make up the majority by weight of aragonite, the mineral secreted by reef-building organisms as skeletal material.
- Continued addition raises pH until 8.3 is reached, at which point the pH remains unchanged and the alkalinity alone increases.
- Over 50% stronger than most competing products.
- Free of phosphate, silicate, and organic material.
- Formulated by a marine scientist.
Brightwell Aquatics Alkalin 8.3 comes in 250 mL, 500 mL and 2 L.
Brightwell Aquatics Alkalin 8.3 Powder
$ 6.49
Brightwell Aquatics Alkalin 8.3 Powder Overview:
- Highly-effective alkalinity-increasing (Buffer) powdered blend.
- Helps increase pH stability in an aquarium by raising the alkalinity; continued addition raises pH until 8.3 is reached, at which point the pH remains unchanged and the alkalinity alone increases.
- Provides a source of carbonates, which make up the majority by weight of aragonite, the mineral secreted by reef-building organisms as skeletal material.
- Formulated by a marine scientist.
- Determine alkalinity in aquarium with an accurate test kit prior to supplementing. Do not add this product directly to an aquarium without first diluting in water as directed.
Technical Background
Alkalinity, also referred to as carbonate hardness or buffering capacity, is essentially a means of quantifying the stability of pH in a solution, such as aquarium water. 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. Maintaining the alkalinity in marine aquaria between 7 - 12 dKH (2.5 - 4.3 meq/L) will generally maintain pH within the desired range.
Brightwell Aquatics Alkalin 8.3 Powder comes in 250 g, 500 g, 1 kg and 4 kg.
Brightwell Aquatics pH +
$ 4.99
Brightwell Aquatics pH + Product Overview:
- Increases pH in marine and reef aquaria.
- May be used to help increase pH in aquaria that have adequate alkalinity yet have chronically-depressed pH levels; while not intended to act as a permanent solution to such issues, pH+ may be used as needed until the cause of depressed pH is discovered and remedied.
- Stronger than most competing products.
- Composed of purified water and ultra-high purity materials.
- Formulated by a marine scientist.
Brightwell Aquatics pH + sizes: 250mL, 500mL, 2L
Red Sea Reef Foundation ABC+ Supplement (Ca/Sr/KH/Mg/K/Br)
$ 21.99
Calcium, magnesium, strontium and carbonate are the basic foundation elements of coral skeletons. All of these elements need to be available in balanced proportions for positive coral health and growth. Reef Foundation ABC+ is a blend of all of the foundation elements with the addition of potassium, bromine and iodine in the unique ratio required by corals.
Red Sea's Reef Foundation ABC+ is a uniquely formulated powder supplement containing all of the elements of Foundation A, B & C, plus Red Sea's Coral Colors A & B (potassium, boron, iodine & bromine) formulated in the exact ratio as found in the coral skeleton. Although there are slight differences between the coral species, the mean ratio between these elements is fairly constant. Supplementing all of these elements in a fixed ratio according to the uptake of calcium will ensure an accurate replenishment based on the metabolic demands of the corals.
Reef Foundation ABC+ should be dosed on a daily or weekly basis according to the aquarium type and according to a measured uptake of calcium. Over time an imbalance may occur between the foundation elements. If dosing daily, you should test all of the foundation elements weekly and make adjustments with the individual A, B & C supplements. If dosing weekly you should test all of the foundation elements monthly and make adjustments with the individual A, B & C supplements.
Red Sea Reef Foundation ABC+ Supplement (Ca/Sr/KH/Mg/K/Br) sizes: 1kg, 5kg
