Obviously drawing conclusions without knowing the facts can cause a foot or two in your mouth. I got my first batch of pellets at a meeting when it was first introduced by wm. I am sure the pellets are good if u use it the right way. Only directions I got was to use recommended amount. When the bacteria colonized it stripped away nitrate and phosphate so fast that my coral couldn't adjust and wiped away alot of the Sps and Lps. It was a learning experience and don't want to make that same mistake w Dr Tim's pellets. I am in the business of helping and stating solutions. Add if it brings worth/value to the thread. Thx.
So now that I have succeeded even after doing what you insisted was the cause of your failure. Maybe you can re-evaluate your hypothesis. I am also in the business of helping and stating solutions. I will give you some help. Lowering Nitrate and Phosphate too fast had nothing to do with your losses! If this were fact, water changes would be detrimental as well. A 20% water change will lower you levels by 20% immediately. Bacteria is fast but not even close to that fast.
