No less that 100 watt. 50's are good for 10 gal max, and they tend to struggle with that.

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.

Specs say 20 gallons or less. I would say between 10 and 20. Anything less and the tank gets too warm from the device. Definitely a good product though. I gave the 9 watt one in my 20 gallon and it works great. I used it to clean up an algae bloom but the specs say "Kills algae, pathogens and harmful bacteria" which may be why the tabs recommended them.

Please be aware this is the lowest wattage unit Farm Innovators makes. If I were going to be looking at 3 gal. and -20 I would think about a higher wattage unit but I have no experience with it in such extreme conditions.

The 150w is rated for up to 79 gal. You could probably go with the 100w unit and be fine, since it's rated for up to 50 gal. This works in my 30 gal with no issues. Best heater I've ever owned.

The 16" light legs may extend far enough, since you only need an inch on either side. The 20inch would or course overhang your tank but the legs could push farther in and fit on the 18". The 20" would give more light output too, I can tell you on my 10g (20"long) tank it provides more medium than low light.

Depends on what you have in the tank and the length. 4 foot wide fish only two 24" light pack will do. If you have coral you would probly want 4 24" minimum. High lighting coral need 3-4 watts per gallon. Most coral 2-3 watts per gallon will do.

20 lb tank is fine. I think you can burn a couple lbs an hour, but it heats up so fast I always turn it off after a 1/2 hr and back on later.

I use 60W Sylvania DOUBLElife, Multi use. They're teardrop shaped. But I bet you could use a lower wattage with no problem. I just wouldn't use a higher wattage.

Kellie is correct. I have a 40 gal tank for my RES and I try to keep the temp at 76. I bought the 150W model an it just spends 95% of its time shut off. I am planning on downgrading to a 100 W so that it can spend 90% of its time shut off and still hold the right temp. The other benefit is that the lower wattage ones are shorter -- my turtle loves to squeeze in and pry the heater off the wall so a shorter one will be more difficult.

Look at the size chart, 300-watt only good to 80-85 gallons. You would need something like 2 500-watt heaters or 1 1000-watt heater. Good luck.

I use a 20watt panel and a voltage regulator. If you have a battery,you will need a solar regulator.

This easily/consistently keeps my 10G tank at 78-80F. Should easily suffice for a 1G tank. You could go w/ less wattage but I don't recall saving much $ over a smaller one.

Its very possible to use this for a 250 gallon I have a 125 and use this 300 watt well below what's recommended for my tank size it keeps it very warm and its very durable I have large Oscars in my tank u can only imagine try contacting a pet smart and see what they think u may have to purchase 2 but its still great at the price amazon has it versus pet supply stores there normally $50-60 bucks at pet for just 1

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.

As far as wattage there is no disadvantage but the only thing you would need to ensure is that the higher wattage heater will physically fit in the aquarium. Higher wattage heater typically means a longer heater.

yes you can use 20lb tank with this heater depending on amount of time required to heat area
