Well I did it and I must say it was nasty. There was times it was literally sucking up pure black. I'm feeling like a real idiot at this moment. I should have known better even though this was the first tank I got started with. I screwed up royally you could say. Through the course of siphoning up all that junk I took down about 50% of the water which is more than I wanted, but the sheer volume of black water brought up from the bottom of the tank was substantial. By no means did I get rid of it all, but I removed a good amount.
I'm going to test the water tomorrow and see where I stand. As always thanks everyone for your continued help.
