Jrittz - sorry buddy, but you are way off base. No one hijacked the thread except for you. All other posts were written about the problem at hand, except for yours, which was intended to chastise only, with nothing constructive to add- and it would seem you didn't even really read the replies, or you would have seen the beneficial information within.
At this point, I think that Lemon is on the fast track to fixing his problem. Why? Because he didn't dump a million plants in his tank. He took an aggressive approach, using water changes, and is now upgrading his system to prevent future problems.
I think we helped Lemon not make a costly mistake by relying solely on plants as a corrective measure for his problem, and informed him of the best, fastest methods of resolving the issue at hand.
Now, with that having been said - Lemon, have you been continuing the water changes? Or did you only do that one? You need to keep them up until the levels are down.
Also, yes. Please let us know the new readings once you have them. I hope things are taking a turn for the better.
