Need help with diy inline heater opinion
I want to use an inline heater for my 20gallon long tank since the intank heaters are too long and are an eyesore as well.
I was thinking about getting that hydor inline heater but I'm worried about the 200watts.
Now I've seen diy inline heaters threads with a list of what I would need to make one but I never see it built or hear about whether they work or not.
So has anyone ever tried the diy method or should I just buy the hydor?
And by the way what is the difference with the two 200w hydor heaters?
