educate hopefully, you - not possible- shoot down what is said as wrong- if it is- yes, and rightfully so, I have no need to back it up- use the fingers god gave you and learn someting outside the little box you live in via the suggested links I provided you. You take this personal - I have no need to do so- my tanks are perfect- have been for a very long time, are yours? I want to share what I know, to help other people- some of you want to tell what you know for what ever reason- there is a difference. It's too bad you can't see this difference. Good bye.
