The first step of nitrification in the biofilter consumes alkalinity and lowers the pH of the system. [11] Keeping the pH in a suitable range (5.0-9.0 for freshwater systems) is crucial to maintain the health of both the fish and biofilter. pH is typically controlled by the addition of alkalinity in the form of lime (CaCO 3) or sodium hydroxide ...
If the probe detects a low pH level, the pump activates. The bubbles raise the pH by dissipating the CO 2 gas. Since the pH inside the reactor is much lower than the pH in the aquarium, you run the risk of lowering the aquarium pH by running a calcium reactor if that low pH isn't mitigated.
Freeze-dried and frozen fish foods were primarily developed for tropical and marine fish and are useful in providing variety to the diet or specialist feeding needs of some species. [4] These include tubifex worms , mosquito larvae , bloodworms , water fleas ( Daphnia and Cyclops spp.) along with brine shrimp ( Artemia salina ).
Raising fish in cages in a lake in a relatively undeveloped environment. Urban aquaculture employs water-based systems, the most common, which mostly use cages and pens; land-based systems, which make use of ponds, tanks and raceways; recirculating systems are usually high control enclosed systems, [clarification needed] whereas irrigation is used for livestock fish.
Alkalinity (from Arabic: القلوية, romanized: al-qaly, lit. 'ashes of the saltwort') [1] is the capacity of water to resist acidification. [2] It should not be confused with basicity, which is an absolute measurement on the pH scale. Alkalinity is the strength of a buffer solution composed of weak acids and their conjugate bases.
In aqueous solution, ammonia deprotonates a small fraction of the water to give ammonium and hydroxide according to the following equilibrium: . NH 3 + H 2 O ⇌ NH + 4 + OH −.. In a 1 M ammonia solution, about 0.42% of the ammonia is converted to ammonium, equivalent to pH = 11.63 because [NH +
Aquarium keepers must make adjustments to the water, food, tank setup, and captivity procedures, as many studies have shown that sea dragons are prone to diseases and infections such as scuticociliatosis, myxozoanosis, fungal infections, intestinal coccidiosis, neoplasia, and swim bladder issues, which can result from parasites growing in their ...
As females increase in length, egg quality and fecundity increase, but egg production is thought to decline after age 6. [7] Sexual maturity is reached between 2 and 5 years old. [3] Other measures of sexual maturity are related to size. A sauger is considered to be an adult when it reaches 250 to 300 millimetres (9.8 to 11.8 in). [6]
