Yeah, they had great customer service. They talked me through fixing my filter, and even replaced my light for me. I'm still undecided about the heater, but I was looking more into some sort of inline heater. They all say they need to be installed on the outlet of the filter, but I was planning on putting it on the intake since I'm going to put an inline C02 diffuser on the out end of my filter. I can't really see a reason why the heater needs to go on the out, but I don't want to not do what the directions say. Is there a reason I shouldn't put it on the intake other than that they say don't?
