Dang, some of you guys are brutal. We know you don't like Neptune, but why do you have to chime in on everyone. We get it. Don't insult us because you don't like it or Neptune. Let fan boys be fan boys. And let people who want to support the furthering of aquarium keeping support this.
As for the maintenance, Terence definitely didn't have enough information for my liking, in terms of concrete pricing/schedule (for a product this is being released tonight). However, I am pretty sure I remember him saying that it won't be required, just highly recommended (and even mentioned potential plans of having a replacement before you send in, but again, not enough information). And then not required that you send it in, just highly recommended. But you buy a probe, and have to perform maintenance on that. You buy a pump, and have to perform maintenance on that. DOS heads have to be replaced. Tubing has to be replaced. Etc Etc Etc.. Why is everyone so shocked that this has a maintenance recommended schedule? And parts are never free, and they will give you the option to do yourself. Doesn't seem like such a terrible system, or am I missing something?
