<p>What items are required for an aquarium?</p>
<p>Lighting
Heating
Filtration</p>
<p>What factors should be considered in choosing a light for your tank?</p>
<p>Temperature and brightness</p>
<p>What are some types of lighting in fish tanks?</p>
<p>Fluorescent - can promote algae growth
Incandescent - not recommended
LED - best choice - energy efficient</p>
<p>What species of fish do not need a heat source?</p>
<p>goldfish</p>
<p>What is the appropriate water temp for most fish that require a heat source?</p>
<p>78-80 F</p>
<p>Describe mechanical filtration</p>
<p>water passes through a screen or sponge
removes debris
EX: under-gravel filters</p>
<p>Describe chemical filtration</p>
<p>Removes yellow color from water wia activated carbon or Zeolite
EX;</p>
<p>Describe biological filtration</p>
<p>natural organisms that break down harmful substances in water like ammonia and nirites
EX: Plants, bacteria, algae</p>
<p>Explain the nitrogen cycle</p>
<ol>
<li>Fish and decomposing material make ammonia</li>
<li><strong>Nitrosomas </strong>turn ammonium to nitrites</li>
<li><strong>Nitrospira </strong>turn nitrites to nitrates</li>
<li>Nitrites stay int he thank until the water is changed</li>
</ol>
