dookie;4821505; said:I've seen countless times where people introduce live rock into their "fish" tank and all it did was wipe out their fish with disease. I don't see any benefit by adding live rock to a fish tank. Of course I'm talking about a tank that does have a real filtration system like a wet dry or whatever. Yes I understand that new reef tanks have rufugium systems with no biological filters other than a skimmer and live rock. I'm not talking about this type of tank. I'm only referring to a fish only tank.
This was most likely not the case. It would not have been disease unless they got the rock from a tank full of sick fish. Most likely they did not properly cure the live rock after purchasing and it caused a cycle in there tank that stressed the fish and made them susceptible to illness. Then the illness that was already in the tank(not from the rock) takes over and kills the fish.
The problems you are associating with rock are not the rock at all and are hobbyist error. Adding rock that is not properly prepared to an already established tank is dangerous. The solution to this is to set up the tank and put the rock in to help the tank cycle. If you are really worried about disease then let the tank stay fallow for at least 6 weeks before introducing fish. This way the diseases you speak of would have starved and be dead. You need to leave the tank fallow almost that long anyway while it cycles so this will solve these problems you have stated.
There is NOTHING that we can put in our tanks that is more beneficial than live rock. It introduces food(copepods, amphipods, etc.), natural shelter, looks, and natural denitrifying bacteria. It comes with more surface area than bioballs could ever duplicate and it also denitrifies deep within the rock. Bioballs create nitrates which is exactly what we don't want in our tanks.
I truly believe that every marine tank should have some live rock in it, reef or no, doesn't matter. It is very important.
