Ammonia poisoning is a common fish disease in new aquariums, especially when immediately stocked to full capacity. Ideally, the level of ammonia (NH 3) and ammonium compounds (i.e. those containing NH 4 +) in fish tanks should be zero. Although trace amounts are generally harmless, they can still lead to problems over time. [1]
Between the blood lead levels of 5 and 35 μg/dL, an IQ decrease of 2–4 points for each μg/dL increase is reported in children. [42] However, studies that show associations between low-level lead exposure and health effects in children may be affected by confounding and overestimate the effects of low-level lead exposure.

An aquarium can be placed on an aquarium stand. Because of the weight of the aquarium, a stand must be strong as well as level. A tank that is not level may distort, leak, or crack. [47] These are often built with cabinets to allow storage, available in many styles to match room decor. Simple metal tank stands are also available. [47]
The Food and Drug Administration followed up with a warning against 17 ground cinnamon products found to contain high levels of lead.
The pump should only be powerful enough to push the water through the filtering material as well as overcome the drag in the intake and return pipes. This makes canister filter pumps virtually insensitive to the height difference between the aquarium and the filter (although exceeding the manufacturer-specified height limit can lead to leaks).
The district's standard of 5 ppb is more strict compared to the state and federal guidelines of 15 ppb, which the U.S. Environmental Protection Agency set as the action level for lead in drinking ...
For a tropical fish tank, maintaining a warm environmental temperature ranging between 75 and 86 °F (24 to 30 °C) enables different tropical fish to thrive at different temperatures. [2] Aquarium substrate usually consists of sand or gravel. Aquarium substrate is important for the fish's health and replicating their natural environment.
In addition to the dozen brands with levels above 1 ppm of lead, 18 brands of various cinnamons or spice blends contained levels of lead ranging from 0.87 ppm to 0.23 ppm, according to the report ...
