Shaker, I'm not saying go by only your LFS. I always get more than one opinion when I have an issue or curiosity. At my LFS, which is amazing!!!!!, there are 3 of the staff I go to, all in the hobby. The owner, who is one of the few owners not just looking to make a quick buck off people, and is actually into the hobby. He will tell me right off the bat if I will be wasting money buying his own stuff. I can be willing to spend almost $500 on a light fixture, and he will turn around and say, that this cheaper fixture is better. In other words although he profits off all sales he has morals. The other two are also in the hobby. Just one probably has 10-15 years more experience than the other. But I will ask them all the same question, and at times get different answers. so when I tell someone they should use the main websites as a source, its just that. Not as the ONLY source, but a source. you can not tell someone on this forum to blow off sources like liveaquaria, which I can guarantee isn't ran by someone who doesn't know their stuff. because fact is: these forums have plenty of people that will state an opinion and not have either facts or experience with the topic being discussed. Not taking credit away from anyone by the way, just certain people.
