i heard from a seller that they claim that the pellets only need water flowing through them, and slowly is fine...even to the point that they clump a lot. BUT in my experience they do not produce as much skimmate nor do they keep the tank "clean" like when they are tumbleing. (clean=no schmoots on the sand and glass)
Once mine got tumbleing again the tank righted its self. However, that being said, the water parameters never changed. Once they started working for me, they have kept the N and P at 0ppm wheather they were clumped and not moving at all...or tumbleing around the chamber. Just the skimmate was noticibly different.
Dave, I have to be honest, even as a skeptic of these things, you seem to be a little off base. Your system obviously is not working with the pellets, but at the same time, I really don't want to blame that on them. As I have NOT seen a reduction in algae since I started using them a few weeks ago, the times when I have had my overflow working for 8 hours or less, until I finally fixed the issue a few days ago, these pellets have increased my water clarity significantly, almost as if I have put in new carbon. I feel like there is another issue in your tank preventing you from results, that has nothing to do with the pellets, but in basic husbandry. And yes I have read this entire thread. While I do enjoy extremely skeptical criticism, I find that your have yet to provide any actual evidence that the pellets don't work for you except that you believe they are worthless.
While I reserve judgement as if these pellets can help us achieve an ULNS system, on not just my tank but others around me the clarity has been an odd thing, and only a few have had problems with an algae bloom (none that have used the BRS) but I can say , those of us that have used brs use their reactor as well and have experienced problems with clumping, but not a significant reduction of flow. At this point I am not concerned about the clumping as long as the flow continues to be strong. I think this is still a very new product, and we have much to learn about how to use it properly.
If someone, I think it was DJ reef, has found success in running them in a filter bag, no reactor, there is something to be said. We DO NOT understand the best way to provide flow to the pellets. There is a few more years of trial and error, or trial and success to give us indication of the best method. These seem to be one of the many things that will be argued on, in which way they should be applied, but my only hope is that through communities such as this we can determine such things.
However, this being said, I can honestly say, your contribution to this discussion has been for the most part useless, detrimental, pessimistic, and in no way useful in our continued trials as to the best way to properly apply these pellets to our marine environment. We keep such a small ecosystem in comparison to a corals natural environment, it almost seems odd that we can claim to replicate it. There might be some promising future to these pellets, but until we can determine the proper way to use them, I can only study and rely on the success and failures of others. What works in one system in no way will always work in another, we are diverse in the way we have set our systems up. To continually say that it doesn't work, these are bogus, etc. etc. Is of no use. Perhaps there is another X factor in your system that is causing. Or perhaps you are right. But unless you begin the process of changing your system, removing one thing at a time, and still have no success it seems odd that you can claim these things are not working. Perhaps you have bad rock, perhaps your sand bed is a detriment to your system, perhaps your sump is somehow accumulating waste. I have spent far too much time testing different methods, equipment, and additives to follow this approach on my on beginner 75 gallon tank. In recent discovery I have found that I have been 95% responsible for most of the issues with my tank, not the things I put into it. In fact when I have properly applied many different methods...they all work...and they all work the same. From probigio, reef-resh, zeovit, vodka, ats, RDSB I have achieved great results for some period of time until my own human error has come into play. With the biopellets now, I am only beginning to assume that faulty equipment and lack of knowledge led to my earlier failure. Now I am not even running activated carbon, but my water looks sparkly clear, with only pellets running.
HOWEVER, I am still reserving my judgement on if these pellets work as effective as all the other methods i listed above, until they bring my problem of HA back under control, as all the other methods have.
What I am concluding is that please, unless you are willing to start accepting that there are other issues in your tank that YOU caused, don't blame a method, because the error more than likely is you, not one of the many wonderful methods that reefers have created to attempt a replication of a natural reef environment:fun2:
