Hello Everyone, Sorry for my delay on getting back to you guys. Work is getting pretty busy so I haven't had much opportunity to pursue this topic. As promised, I posted a request on Dr. Ron's forum over on RC. You can read his response at: http://reefcentral.com/forums/showthrea ...

Hello Everyone, I have spent far too much time at work today searching the literature and finding information on phosphorus regeneration in sediments. All I can say is that I am very humbled by the amount of information that is available in the scientific literature on this topic. I thought...

Is there data that shows that it is not what happens? That is to say, is there any study that compares different nutrient processing mechanisms between sand beds with and without the benthic infauna? We have two conflicting claims here: one that the DSB is inherently a phosphorus sink, and...

I have to be careful that I don't get us buried in a circular debate here. My understanding of the DSB theory is that the critters in the sand process the phosphates so that they are either A.) insoluble and no bioavailable; or B.) soluble and go into the water column, where they are then...

Hell, I'm still reading the first thread. It takes awhile since I have to look up so many of the words that Galleon uses. :wink: Ok, I think that we are getting somewhere here. My understanding so far is that the phosphate is basically released into the water column or bound as insoluble...

Thanks for the link. I will read through it before posting any more threads. It looks a bit long, so it may take me a day or so. One thing that I don't understand. Many people state that DSB's are "nutrient sinks" or "phosphate sponges". I just don't get this. I don't understand why the...

Depending on the size of the snails, 20 snails could easily be too many for your 55 gallon tank to support. A common series of events that people report in cases of mass snail death goes as follows: 1.) Lots of snails in the tank doing fine for many months 2.) Snails start to die 3.) Massive...

Carbon based compounds are oxidized to carbon dioxide gas. Some of this carbon dioxide might be used by photosynthetic organisms, but the rest goes into the atmosphere. Nitrogen based compounds are oxidized to ammonia, then nitrite then nitrate. Anaerobic bacteria reduce nitrates to nitrogen...

I don't think that it is a matter of the DSB getting full or recycling the goo. Based on everthing I have read on DSB's, there are sufficient export mechanisms to account for all of the inputs. I think that the issue is that some DSB's may stop working because the waste processing capability...

Hey Bob, I have switched to Randy's two-part recipe and it seems to be working great. With respect to your question, you can usually raise the level of the calcium in one shot without causing a big swing in the pH. On the otherhand, the alkalinity should be raised very slowly. I have found...
