The deal here is what marketing tells you, and more often confuses you. When I was starting less than a year ago, I was SO confused, so overwhelmed. EVERYONE has an opinion. Most shops will tell you everything else is crap but what they sell. Meaning every brand is the best and also every brand is the worst. What I started doing was looking to peoples tanks, looking through their posts, what they have, how things are looking and HOW LONG they have been using it. What parts were breaking, then SO hard to find, or were discontinued. Needle wheels, pumps, etc, etc. Customer service from XYZ company, etc, etc. All while trying to block out the noise of the marketing hype and the next gadget. This is how I got to my decision anyways.
I just actually cleaned mine. The stink is still in my nose. Haha.
I'll post a pic in the tank of the month thread. Wish I took a close up. Thick and nasty.
