I need help on my Aqueon aquarium submersible heater for my 20 gallon tank?

i just bought it and i did as told in the instructions.
I placed it in the tank horizontal cause of my caves and plants.
anyways, it says that i will find the heater working if the red light will come on.
i turned it on after i waited 40 minutes so it can adjust to the temp. of the tank.
after i turned it on, the light didnt come on, so i had to turn the heater nozzle to 74*F.
the light came on but a while maybe 30 min later, the light went off.
is this normal?
the heater is a 150 watt.
and the instructions also says that it will turn on when heater something.,
is this normal???
please help.
thanks for your time

That is perfectly fine, the heater only works when the water needs to be heated.
say u have the heater set on 75, if the water temperature falls below 75 degrees the heater will start working,heating up the water and the light will come on.
The light isnt on because the water temperature is higher than wat u set it to on the heater so the water doesnt need to be heated because its already at the correct temperature =)

In order to prevent excessive green pond water, caused by planktonic green algae you will need to use an ultraviolet sterilizer or ultraviolet clarifier. UV light is the only real solution to effectively control the build up of suspended algae types. It is important to correctly specify the wattage of the UV model in order to save money and to ensure that the UV model is powerful enough for your needs. Apart from ruining the appearance of your pond, algae blooms can be particularly harmful to your pond fish and nutrifying bacteria.

What Is The Difference Between A UV Sterilizer And A UV Clarifier?

Please note that these terms are often used by sellers to mean the same thing. I believe the confusion arises from the fact that they are both used to control green pond algae.

* The major difference between the two is that a UV sterilizer, as the name suggests actually sterilizes (sanitizes) the pond water by using ultraviolet light to kill parasitic pathogens and other water borne bacteria. They are generally used in large Koi ponds where the levels of bacteria and other pathogens are much higher. They are also usually fitted with much more powerful UV bulbs. A UV sterilizer also rids the pond of unwanted suspended algae.

* A UV clarifier does not destroy bacteria, viruses and other pathogens. It has been designed solely to destroy green planktonic algae. It destroys floating algae by bombarding them with ultra violet light, which breaks down the cell walls. This kills the unicellular algae, causing them to flocculate (clump together). The clumps are easily removed by a biological pond filter, pond skimmer or by some other means. They are usually used in small to medium sized ponds and tend to have smaller wattage UV bulbs.

As a rule of thumb the following guidelines can be used to help you make an informed choice. Please note that I am talking about UV models fitted with a quartz sleeve. UV light works optimally at around 40 celsius (104 Fahrenheit). Its efficiency is affected by temperature. At 20 celsius the same unit will only work at 50% of its maximum efficiency. A quartz sleeve allows UV light to flow through it easily and ensures that the temperature remains at 40 Celsius, despite the pond temperature.

* If you have a small garden pond up to 250 gallons which is located in full sun and is highly stocked then a 4 watt UV Clarifier with perform adequately.

* If your pond has a volume up to 700 gallons and is located in a shady spot, with only a few fish and they are mainly goldfish then a 4 watt UV system will be ideal.

* A medium sized pond up to 1200 gallons with an average fish load will require a UV clarifier with an 8 watt bulb.

Please note that the above is a guideline but will be ok in the majority of cases. If in doubt always choose a higher wattage UV unit. The running costs may be slightly higher but will be significantly cheaper than replacing expensive Koi that have died due to algae blooms starving the pond of oxygen.

The following factors will also influence the power of the UV clarifier or UV sterilizer needed:

* Warmer climates with lots of sunshine such as those found in the southern states of the USA and California will benefit from using a more powerful UV model.

* Heavily stocked fish ponds, particularly those with Koi, that produce much more metabolic waste than an equivalent sized goldfish will benefit from more UV.

* In fish ponds where the water temperature is maintained at 20C (68F) for long periods of time you should consider using a higher wattage ultraviolet clarifier or UV sterilizer.

* When you have the above 3 factors in combination then you will definitely need more UV light in order to prevent algae blooms from developing and turning your pond water green.

If you already use a UV unit to remove floating algae but the algae blooms appear to be increasing then the following pointers will help you to get things back on track!

* Have you been using the UV, continuously for some time? A typical UV bulb will last approximately 1 year, if used 24/7. You may need to replace the bulb.

* Clean the quartz tube, making sure that it is transparent. A garden pond contains lots of fine particles. Some of these particles will stick to the quartz tube. When this happens the UV is unable to subject circulating pond water to the full UV intensity available.

* Have you added more fish to your pond, or have the fish grown in size? Perhaps your existing UV is no longer powerful enough for your situation. The following options are open to you: You can get rid of some of the fish; or replace the existing UV with a more powerful one or buy another UV with the same wattage as the original and pipe it in series with the existing UV unit.

* In the colder northern states of the USA and Northern Europe it is ok to shut down the unit in winter. In fact in places where ponds freeze over it is a good idea to remove it and store it away until spring.

A word of warning! Ensure that you place your pond pump and Ultraviolet system on the same electricity circuit. If the power goes and your pump stops working this will prevent the UV from running without water circulating through it. This will prevent deposits from forming on the quartz tube surface, due to the water evaporating.
