which wattage do I need to get for a 20 gallon tank? Can they be put horizontally?
2018484
The 100w should be sufficient. Not sure about putting it horizontally but recall reading somewhere that you can.
2018485
I use 100w for my 20-gal according to box (box keeper here) yes vertical or horizontal

You need a 100 watts for a heater and I don't know never tried it I am sure it don't matter I do know you can have fully under water

If you search for Aqueon Pro heaters on Fosters & Smith and they have a sizing table there. It indicates a 20 gallon should use a Pro50 - that's their 50W unit. I sized mine up, in anticipation of getting a larger tank for our turtle down the road - something you might consider. And yes, they can be mounted any orientation you wish. Mine was submerged horizontal for a year, then we moved some things around and now it's on a 45 degree angle - the suction cups that attach it to the side of the tank make it easy to mount any way you want. These heaters are pretty rugged and have some nice features - I highly recommend them.

I have a 20 gallon aquarium also and I have a 100 watt but you could probably get away with a 50 watt. I always set the heaters up vertical so really couldn't tell you on that

I got the same tank as you and ordered these last year. They work pretty well for my heavy planted aquarium.You don't need to set it up separately. All you need to do is to clip the new light onto your original set up.

A 150 watt heater should suffice for this size of tank if you are going to keep tropical fish not cool water varieties (such as goldfish). The main thing to remember is to keep a constant temperature and water conditions. I listed below a few good websites for beginners. My advice is to do a lot of research on the fish you want to keep and set the tank up appropriately to the types you want to have. Also remember to cycle your tank before adding any fish and after the tank is up and running do regular water changes and tank maintenance.

Hello. I wanted to start by noting the heater I received is not the one in the picture. It is shorter and thicker, and only has one suction cup at the top.That said, I bought this one because it was the lowest wattage I could find for my 1 gallon tank. The recommendations I found said 7 watts for 1.5 gallons and up, 5 watts for 1 gallon and up. I have not seen any for smaller tanks than that.

Check dimensions of your tank before you decide, my 250w is fairly long I have. 40 gallon breeder, works well, I think 150 or 200 watt will be okay in your tank but again check dimension of tank and of heater to see if it fits vertically

You will need at least 2 for sure. I have a 30" tank and one just barely does it. If I had room for another one I would put acsecondbon the tank to get better light at the bottom.

I'd personally get a smaller one. This article says 100watts is too much for a 10 gallon tank. Here's the reference article - http://www.thatpetplace.com/fish-tank-heaters-article

you can use the 12" if you want the light to go front to back, but ideally, we need the length of the tank since most lights run parallel to the front glass.

In my 120 aquarium I used the 250watt. Going a little bit on the large side allows for a more stable water temperature. And yes, heaters can be placed in any direction, including horizontal or upside down, and still work.

They are air cooled. Used Indoors only at this wattage and voltage if they are 110 volts. They do make a style for outdoor lighting that is low voltage. but if this is a 50 watt 120 volt then it must be used in dry location indoors not outdoors where moisture can get to it. If it used in a sealed water tight fixture outdoors then maybe ok...but double check your wattage in the sealed 110/120 volt fixture make certain it does not say 20 watt. A sealed fixture can get too hot out doors too.

Sure you can, they are 10 watt each. However these lights can't be used underwater as advertised. I have several and did get some replacements because they are not designed to work underwater. You need to encase them in something that I have not found yet. They mainly leak around the electrical grommet.

Depends on tank size, mine is over a 20 gallon tall, and is successfully lighting duncans, hammer, and various favia and favites. Also look at the reef breeders nano par 38 lamps, they're not too much more $.

very low wattage, those long bulbs that are like 15-25 watts. or you could use a small hear pad on the bottom or side of the tank. OR nothing at all depending on how warm your house is!!

There is a chart on K&H;'s web site that you can use to fugure out what size watts you need for your pond and area.Good luck.

LED lights have no listed wattage. Mine is a 20 inches with two sets of LEDS for a 35 gal aquarium-no live plants.

Two choices. Either two 100 w heaters at opposite sides of the tank or a 200w should work. These heaters are powerful and heat better than other brands of the same wattage.

The standard for wattage is 3 watts per gallon of water. If the aquarium is going to be in a cooler area of the home you may want to consider 5 watts per gallon.
