All,
Recently, the new trend in high end SPS keeping is to utilize some type of probiotic filtration method. This originally was only accomplished through the Zeovit method (www.zeovit.com) but quite honestly, the technology behind doesn't make any sense to me, and there is way too good a chance of nuking your tank. Another factor is the hefty price tag.
I've come across two new companies marketing new products and wanted to let you all take a look at them as well. The first product is called Prodibio and all information and sales are going through www.robsreef.com . Marc Levenson (Melev) of DFWMAS is currently experimenting with this method and I'm very curious to see it's effects in his tank.
The second is called System Reef-resh and is distributed by a Canadian company at www.polyplab.com. They also have a high quality soft coral food that I should be receiving any day now. Check them out as I think they are quite possibly the next filter additive.
