i think it does, because whatever system one uses reflects on ones tank same with saying that other are useless without showing a better way. but then people using "useless" methods have great looking tanks and are willing to post picture of them.
and i don't care what people use, be it Zeovit, MM, vodka, draino, cheap spanish red wine or battery acid. if they have success with it, great don't knock it.
i go around to other reefers and judge their tank not on size, method applied (i.e. vodka) or all that fancy equippment they may have(or not). but solely on their success with keeping and growing corals. may be instead of showing all those beautiful corals people grow we should put up a list of the ones that have died in our tanks. and compare the mortality to the methods that are applied!
some people will have no doubt pretty long list. :-?
others keept them with absolut minimal losses. and i think this is something we should try to achive first of all. so go the system that works best for you and mostly your corals!
i show people my tank and tell them what i use (Zeovit) without pressuring them to do the same. let them decide what to use. its a free world!!!
