There are many aquarium heaters you can buy online. I want to give you all a fair warning… Do not think you got a great deal when you purchased that 300 watt aquarium heater 8 dollars. I tried that route when i was setting up all my breeder tanks thinking, “Great! Ill get all these cheap heaters and ill have my tanks up in no time”. Well, actually 3 out of 4 of these cheap Chinese water heaters didn’t even work coming out of the box. I had to wait a month to get these cheap heaters as they were shipped form China. I returned them and they gladly issued me 3 more. None of them worked. This is one little item you don’t want to cut corners on or you will wake up one day and your fish are in 55 degree water. Stick with brand name aquarium heaters. The very best aquarium heaters are the titanium heaters. The are durable and wont crack if dropped or overheated during a water change. I have a few aquarium heaters that i would like to recommend to you. Please check them out.

Note: People ask me all the time, “What is so great about a titanium heater”? The answer is simple – Durability!! You see, if you are keeping fish that can grow to excess of 2 pounds or more and the begin to splash and thrash as part of their spawning ritual, they tend to break glass lined aquarium heaters. Now if you remember that you have live electrical current running through your aquarium heater, you will have a short circuit occur, which in turn means your power to your fish’s tanks have just been shut off resulting in either fish that have died from cold water or more possible from no heater, filtration and most important in the short run, no oxygen!
