Hello everybody,
I'm the person that developed the biopellets and to answer some questions:
-The pellets don't dissolve in water in the absence of bacteria
-they do not stimulate bacterial or algae growth in your tank and specially for the algae growth, this appears to be reduced and similar observations have been done for cyano bacteria when compaired to using soluble carbon sources such as wodka or sugar. big advantage is no more bacteria growth on your corals and unlimited carbon source to reduce nitrate and phosphate. My own tank consists of gorgonia combined with lps and sps corals. this requires feedings of 10x a day (with reefpearls ;-)) and I can keep nitrate between 0-5ppm and phosphate around 0-0.03 without the addition of wodka and phosphatekiller. this was for not possible before I started to use the biopellets.
-they are heavier than water and can be used in fluidized filter systems. we recommend this actually because this way you will always have high water flow and thus more aerobic conditions for your bacteria, which in principle is much safer than anaerobic conditions. On this point we have to say that some anaerobic bacteria will excist on the pellets, but this layer is so thin that is not harmfull and has a rather positive effect on your pH (aerobic-> H+; anaerobic -> OH-)
- the pellets are not on the market yet and will be released soon in the netherlands and belgium and other countries will hopefully soon folow. until that time you can contact me for questions at
info@reefinterests.nl (I hope this allowed by admin, otherwise I apologize and please remove just this last sentence then).
-in contrast to what was mentioned, the pellets do not need to be replaced after 6 months. they are consumed by the bacteria and will slowly disappear, which means that you have to add extra pellets every 6-12 months. In one of our test conditions it took 3 years to completely digest the pellets. this is also the reason that you have to use at least 1 or 2 liters of these pellets (around 120 euro's) but it will last at least 1 year.
Wodka can still be combined with the pellets and will rapidly be consumed by the bacteria which live on the pellets, however, it is not necessary to do so, but when you need to finish the bottle of wodka, this is one way of doing it ;-)
Don't hesitate to ask any questions when things are not clear.
ciao,
jean paul
