IS the Medium Sized good for a 20gal tank? I have a small, but its not heating the tank at all. The temp. is 70f and it needs to be over 75f for my BP

It's dependand on the temperature around the tank environment. These heat pads also don't heat as well as they age.

I would stay with the smaller heating pad cause they need cool space as well plus its really the lights you use that should keep the temperature of the tank to be over 75f.....not the heating pad (this is for when they are cool and want a place to warm up) I would check the watt of the day light u are using and maybe use a 75w or a 100w day light for reptiles and use the same watt for the night light(red light)

You will need the small for 10to20 gal tanks. Connect it to a reptile thermostat to keep the temp up. I keep leopard geckos bluetongue skinks and many more species and that's how I use them... rm temp is around 70to73° and the thermostat is set for my aid animals at 92° and for my tropical and temperate animals at 80 to 88° thermostats are key to success.

I bought the Aqueon AQ10W. It seems to work quite well. It is about $15. I do not like that it is automatic and in summer it keeps the tank a little warm (about 85F). It doesn't seem too hot for the bettas, would prefer to be closer to 80F but they seem healthy and happy.

There are heaters that work like a heating pad but they they don't work very well. So I would recamend getting a thermomitor as well. Betta can handle water temp as low as 74 and up to 84. An other option would be to get a real aquarum heater and a dish wash tub. During the evening or on really cold days put the whole no clean aquarum in the tub full of water and the heater. Good luck!

I am using 150w for a 40 gal tank (but it has only about 20 gal water in it).

I bought a Marina C10 Submersible Aquarium Heater, 10W. It works fantasticly. I put it inside the white tube, behide the filtersthere is plenty of room and it fits just right. The temp. stay constant and my betta LOVE this Aquarium.

It won't work for your application. This heater is meant for indoor tanks. For 200gal at 20F you'll need some sort of de-icer.

For a 150 gallon tank. I am assuming that it is fresh water, but either way, I would purchase 2 - 300 watt eheims. If you have returns, I would place one in each. The reason why two is for redundancy if one fails. I have two setup on an Apex system and can keep the temperature constant at +-2 degrees. Also if you have to elevate the temperature of the tank to cure something like ich, having the two heaters will ensure you can take the temperature up.

Hi -- I have a 2 gallon tank and it is working good. I recommend buying a cheap additional water thermometer and then setting the temperature on the heater to be slightly lower than the desired. For example I set my heater to 74 to get an actual temperature of 80F (as measured by the second thermometer).

You would need the 5 watt size for a 1.5 gallon tank. This one would be way too warm.

I have this model heater in a 38 gallon Bow Front Tank and it keeps the temperature right where I want it. I would say the accuracy is a bit off. For me to achieve 75 degrees in the tank I have to set the red marker/bar fully into the 79 range. I haven't tried a larger heater since this is just fine, but maybe a larger heater might not run as long to heat up the water. Mine "does Not" stay "constantly" on with 38 gallons at 75 degrees, it does turn off.

Mine has been submersed in my 55 gallon tank for almost a year. The water level comes just above the dial and onto the cord. I have not had any issues with it heating and my thermometer and heater settings are dead on. I would buy it again. 300 watt version for my 55.

The 10 watt is too much for your tank. I had mine in a 3 gal and it was too warm.

I'm not by the thermometer right now but know it goes well abobe 90 (likely about 100) and then well below what would be recommended for colder levels. I've been very happy with it so far, and have been keeping the tank at 84-86 degrees for my discus fish which like a warmer temp. Would buy again and the price seems right.

I have a 750 watt. I live in mid Michigan. I have it on a timer for 12 hours at night. It keeps a open area usually about 2 feet around the heater (pond is less than 3 feet deep there) most days. When its really cold, the circle shrinks. My fish seem to do fine: I have it near the rock pile they hang out in. You could go a higher wattage or just have it run longer. I got it in 2011 I believe so this will be its 3rd winter. good luck

A single 150 would work. These never get very hot but just put it where your have the highest circulation. I have mine next to a U4 submersible filter in my 50 gallon tank. Quite frankly, I keep my place warm/cool all the time, 68-80, so mine probably does not come on a lot anyway. If you have African Cichlids that would be different but I just have SAE, Platys, Japanese trapdoors, etc. which like it in the mid 70's anyway.

This 150 watt will work for your tank. Most sources suggest 3-5watt per gallon. Lights create heat and regular room temp affect the waters average before heating. Mine doesn't come on much in the summer at all. If tank is on an outside wall it will be colder than the middle of your house. Same for if you live in warmer area like Texas vs michigan where it's always colder. I'm using it on a 75gal right now. Will add another in winter if it can't keep up.

Mine heated my 5 gallon tank in a few hours. Something is probably wrong with it if it's been on for 48 hours. Try returning it.
