Koestby --- I ran out of the first bottle of Nopox and didn't dose for two months. Nitrates remained very low and phospates rose from 0.43 to 0.81 (much lower than what they originally started out at). During those two months, I started to have a few patches of GHA, but nothing to get worried about. I received another bottle of Nopox about 4 days ago and started dosing again. One thing of interest is that while carbon dosing, my pH came down from 8.4 to 8.2. Over the two months I stopped, it crept up to 8.5. After 4 days of the new bottle, I see pH coming back down again. I must say, I have been overall pleased with the experiment.
Frankb1 --- I absolutely love the TBS rock with the amount of life it came with. Is it perfect for getting a very beautiful aquascape? I guess that is a matter of opinion. While it doesn't have perfectly cut shapes to make a nice, crisp look, I am happy with how it looks in my tank. If I had to do it again? Yes, I would go with TBS. However, since I would no longer be starting out, I would have a separate tank to keep the rock in and thoroughly inspect for bad HH. Once a rock was declared "clean", I would move it to the display tank. A much slower process for starting out, but you wouldn't be hunting down as many gorilla crabs and such. In fact, since I have a system set up, I very likely would removed a few of my rocks and use them to seed dry rock.
