It is a measure of the acidity or basicity of the water. The scale runs from zero to 14. Zero is the most acidic. Seven is neutral 53 alkaloid biology chemistry volume and 14 is the most basic. The pH scale is not linear, but logarithmic. A change of one pH unit, for example from seven to six, means that the water gets ten times more acidic.Due to its chemistry, salt water is able to absorb a certain amount of acidic matter without a resulting change in pH. The substances in the water that do this are called buffers. The ability to withstand changes in pH is called buffer capacity. Based on a method of measuring buffer capacity, it is referred to as the alkalinity of seawater. In some of the literature alkalinity is termed "carbonate hardness" or "kh carbonate buffer". This is exactly the same measurement as is measured in the Alkalinity Mini-Lab test.pH And AlkalinityThe pH of natural sea water varies geographically in the world's oceans between 8.1 53 alkaloid biology chemistry volume and 8.4. On a local scale the pH is however remarkably stable. This is due to the dissolved buffers (mainly bicarbonates), which prevent pH changes. Because of the enormous volume of the ocean, a nearly inexhaustible stock of buffers are present. The sea can take up large amounts of acids without a noticeable change in pH.Compared to the sea the volume of a marine aquarium is very limited 53 alkaloid biology chemistry volume and therefore the alkalinity is also limited. As fish produce acid waste products 53 alkaloid biology chemistry volume and as the buffering substances are used up by calcareous algae 53 alkaloid biology chemistry volume and invertebrates, the buffer capacity may become so low that the pH could suddenly fall. This would be very dangerous to all organisms in the aquarium.The alkalinity is measured in so called milli-equivalents of alkaline substances (for example sodium bicarbonate) per liter. These alkaline substances have the power to prevent pH drops. The alkalinity of natural sea water is approximately 2.5 milli-equivalents per liter. This level should also be maintained in the marine aquarium.A common symptom of an unsuitable pH is pH stress. Especially in the marine aquarium, unsuitable pH values are very stressful to fish, 53 alkaloid biology chemistry volume and increase the chance of the fish being susceptible to disease (marine white spot). To maintain a correct 53 alkaloid biology chemistry volume and stable pH, check the pH 53 alkaloid biology chemistry volume and alkalinity weekly.

Hagen Aqua Clear 70 Aquarium Power Filter (300 GPH) Quiet, efficient 53 alkaloid biology chemistry volume and reliable Aqua Clear 70 pumps 300 gph. Recommended for aquariums up to 70 gallons. Aqua Clear stands alone as the only aquarium power filter that offers the integrated filtration of the CycleGuard Insert System. Aqua Clear combines the largest volume of efficient filter media in individual inserts with the powerful water flows from the free floating impeller. Alternate replacement of the CycleGuard inserts ensures continuous biological removal of organic toxins can be achieved. The waterfall style output from the Aqua Clear filter agitates the surface of the water while creating beneficial currents throughout the entire volume of the aquarium. Both the surface agitation 53 alkaloid biology chemistry volume and the rotational currents bring more water molecules to the surface, in physical contact with the atmosphere, enabling them to release carbon dioxide 53 alkaloid biology chemistry volume and replenish oxygen more efficiently. In addition, the constantly moving water currents do not allow dead spots to occur in the aquarium, eliminating the possibility of thermal layering. Water input per hour is regulated by adjusting the patented flow adjustment mechanism, tailoring the flow rate to the aquarium's requirements. When the flow adjustment reduces input, the water returned to the aquarium is still equal to input, but the top grid in the filter basket circulates purified water back into the motor chamber so that the pump filters 300 gallons per hour even when adjusted to siphon less. Water may be filtered more than once without reducing the actual flow rate of the pump unit. The Aqua Clear 70 actively draws dirty aquarium water through the integrated siphon/strainer assembly into the pump impeller chamber. The flow diverter directs the powerful water current from the impeller chamber under the filter basket. The water is forced to move through the provided filter media 53 alkaloid biology chemistry volume and then returned purified to the aquarium. Aqua Clear Power Filters are designed to fully exploit the benefits of removing aquarium wastes both mechanically 53 alkaloid biology chemistry volume and biologically. The recommended CycleGuard filter media, when used 53 alkaloid biology chemistry volume and rotated as suggested, ensures that both mechanical removal of particulate matter 53 alkaloid biology chemistry volume and biological filtration of ammonia 53 alkaloid biology chemistry volume and nitrite combine for proven beneficial results to all aquarium inhabitants. Aqua Clear's unique CycleGuard system offers maximal amounts of time proven filter media to perform the assorted purification jobs required for optimal water conditions in the aquarium. CycleGuard inserts break the water stream into many ever-changing channels, passing through the entire length of media before being returned to the aquarium. The CycleGuard Media Step System provides extremely effective mechanical debris removal. The screen size for particles reduces with each step, trapping the large particles first 53 alkaloid biology chemistry volume and the fine ones deeper in the chamber. The Step 1 Foam traps larger particulate matter before it can clog 53 alkaloid biology chemistry volume and block other inserts. Step 2 Ultragrade Activated Carbon adsorbs liqu
