@TheFishGuy Trolls happen all the time. They are the ones that pop in and ask about an already established (usually) controversial topic.....then proceed to argue with us or say things that get us riled up and want to argue with each other. Trolls are out there trying to sew dissent. Why? Because they can. Robots happen all the time, as well. They are the ones that pop in and ask some off-the-wall questions about a product....that most of the time, no one has heard of. They will post direct links to products or web sites that are a way of saying, “look at what I am touting.” Then, if they’re lucky, there is another robot that (again, someone brand new, who has never posted) will answer and you suddenly have this dialog going between 2 brand new members about something that apparently only the 2 of them are familiar with. For the most part, robots are trying to gain access so they can sell a product or look for a target audience. With both trolls and robots, you usually never hear from them again.
Maybe the fact that the question, “what kind of filter,” was followed by the centipede and snorkel question — since centipede and snorkel play into a very specific type of filtration system..... And then asking about building one from HD parts? And yes, you are correct to be a glass-half-full kinda guy....but as you get older, you will likely start to see through these scams and will start questioning things (again, as you should). There are a lot of trusting folks on the internet, and unfortunately, a lot of people out to take advantage of them. Step 1: get your foot in the door and gain trust. (Like the text I received 2 days ago saying that I had won $500,0000 and to contact XYZ. Notice how the monetary value was typed? Yes, the comma was sorta in the wrong place — I’m still laughing over that one).
I hope the OP is legit, and if he is, that he isn’t offended by my skepticism and will stick around and become a valued member of this community.
@miogpsrocks, I do apologize.
