its not useless. you have to look at erics idea of what a fuge is. its not how many, even most, others view it. for him nutrient exporting is not what a refugium is for. for him a refugium is only for growing "small crustacean life".
a refugium with only macros is pretty much useless for him, as it doesnt provide the ideal place for pods and things to propagate. for many others, growing macros for nutrient export(mainly phos) or to aid with ph stablitiy(CO2 excess) is the primary purpose of their fuge. in erics mind this is not a refugium at all, even though you are growing organisms in a predator free environment that would otherwise be eaten in the DT, even though that is the definition of a refugium, but because its not for growing crustaceans to feed the tank its not a refugium in eric's eyes. for him its only about the crustaceans. macros are only for pods "crustaceans" to feed on and hang out in/on. there are some that even grow macros for the sole purpose of feeding it their fish, but eric would say thats not a refugium dispite his definition " refugium is a place provided to allow certain organisms to grow while freed of predation or herbivory. ". nutrient export is just a small supplemental benefit not a purpose of a fuge to him. i dont buy that at all. i dont know that he does either, as he saves himself by stating
in his words;
"its supplemental though it can be signigicant"--
for powerheads in framerguy's fuge, that is the part of careful condideration, wouldnt you think, at least for famerguys wants/needs, that is increased exporting of nutrients.
some double talk, his words here;
then followed up with this;
its just his interpretation of the definitions. he veiws placing a coral in the fuge as if it was a predator and renders the fuge useless
if i decide to place only macros in the "refugium" so they have a safe haven to grow without being eaten, still not a refugium??,,, but i thought--" refugium is a place provided to allow certain organisms to grow while freed of predation or herbivory. "
i dont know what orgainisms count in his mind. jsut because the the refugium is not meant to cultivate pods to feed the tank does not mean its not a refugium or is a useless refugium. for me a refugium is more than just a place for pods to grow--technically it seems he considers breeding pods in a "sump" not to be a refugium either. his words---"If one desires to keep an area for breeding or propagating organisms, it might be a tank that replicates a habitat and that may look like a refugium - but it is not a refugium"___with that, what would be refugium if not for breeding and propagating. he states "a refugium is a place provided to allow certain organisms to grow while freed of predation or herbivory."--macros grow, not a refugium though. mmmmmmmm but then pods and crustaceans breeding and propagating is not a refugium either, though it looks like one:jester:
FYI; in the opening statement his gives some misinformation, the first refugia was used by Jürgen Haffer during the 1960's in the amazon river, not by Smithsonian Caribbean mesocosm in the 1980's as erics recalls
.
not bash eric, he has done a lot for the hobby. but opinions well everyone has one
