well... let me thank all of you who helped me in the past 3 months. Thank you. To mention a few: Wendy, ReneeRN, Adam from Wallington and others. Also my wife who put up with me and my hobby lately. After reaching ammonia 0, nitrate 0 and nitrite 0 - i decided to change everything. I broke down the tank, cleaned, bought new lights, new sand, new live rock new wavemaster. I set up holding tank which will be a QT tank before anything comes to main tank. I do not take good pictures and the ones I took do not show truly what it is right now. But I will be posting updates regularly.
