Now that a layer of sand is well known ...

Gravel vacuum has been long and

important part of equipment for the fans who still use U nder G Ravel

(UG) filtration. Gravel vacuum is the best way to remove trapped

gravel with gravel from the aquarium filter UG. Today

modern aquarium that does not use UG filter gravel vacuum can lead to

bad influences that include the removal of beneficial organisms, violation

ecological balance of the beds, crutches in ammonia and nitrites, and death

your fish a few days after cleaning. I will go into small details >> << beds of sand and the overall importance it plays in health

aquarium eco-system. As you can see, I use the term sand bed instead

gravel. Sand has many advantages over the gravel in fresh and salt water

system. First, it helps to keep debris on top of the bed to power

filters can remove it from the tank allows it to be removed from the system >> << when cleaning the filter. It also helps

N atural N itrate R release (NNP), allowing only very purchase strattera slow exchange of water through

bed. A slow exchange of water through the sand layer allows two

important and various environmental groups to develop. The top layer of bedding >> << that is in contact with oxygen-rich water is largely colonized by bacteria nytryfytsyruyuschyh

Nitrosopira and Nitrospira genus. These bacteria are responsible for converting

ammonia and nitrites in the aquarium many times less toxic nitrates. Without enough of these beneficial bacteria in your aquarium >> << ammonia and nitrites will shoot to the toxic level of killing fish. >> << The bottom layer is a special type of bacteria called anaerobic bacteria. Anaerobic bacteria >> << live in an environment where there is no oxygen available. In

aquarium anaerobic bacteria use the oxygen atom of a molecule of nitrate, the

through conversion of nitrates into nitrogen gas (which will bubble from the reservoir).

To these two different layers exist in a layer of sand must have

fine sand 2 inches or more in depth, and organisms that may help to slow water exchange >> << through the bed. A layer of sand should be deep enough to allow >> << aerobic bacteria (

Nitrosopira / Nitrospira) and other organisms use

oxygen to reach the deep layer of the bed. For this reason, >> << to fine sand and gravel to quickly exchange system >> << that makes it much harder to develop anaerobic layer. Although it is possible to have anaerobic layer of gravel takes 6

to 12 inches for this purpose. Now that organisms help with

NNR. In seawater, there are many species of tube worms, snails and other

errors that help to slow exchange of water through the bed. In freshwater >> << are snails (Malaysian Livebearing snail), fish like Cory Cats

and Golts, worms (California Black Hearts / tubifex worms), and other errors. As you can see a layer of sand is very diverse ecosystem with all organisms

interdependent of each other to keep the aquarium water chemistry safe for your aquarium inhabitants <<. >> Now, when a layer of sand is well known here >> << gravel vacuum. STOOOOOP! Gravel vacuum should be used only to haul gravel from >> << that may be laying on top of sand. If push

gravel vacuum in the sand or gravel in the aquarium you'll be pulling

beneficial organisms, disrupting your anaerobic layer, and worst of all your >> << degree colonized by aerobic top layer will no longer will strongly colonization

aerobic bacteria. Move forward a few days as your aerobic bacteria

population that is in contact with the water layer much

five days after such treatment early loss of fish lovers. Now you need to do

90% water changes to reduce ammonia and nitrite concentrations down >> << to an acceptable level for fish. It may take several weeks for

aquarium eco-system to recover from such a cleaning, so you will need to verify

water for ammonia and nitrites every few days and help feed
