Reef Safe?

I'm a newbie at SW. What does reef safe really mean? Does it mean the fauna won't hurt the coral? Does it mean the other way around? Does it have to do with aggression or venomousness?

It has to do mainly with the fact that aggresive fish will eat the corals and rip them apart as far as I know.

Just to clarify a bit, whether or not the fish is aggressive really doesn't have anything to do with being "reef safe". There are plenty of peaceful fish that are not reef safe. Reef safe just means the fish won't eat coral.

I would also add reef-dwelling monbile inverts such as shrimp, crabs and snails to the list along with corals. There are some fish that will eat both, some that will leave the corals alone and some that will leave the mobile inverts alone. Best bet is to stick with fish that will leave them all alone.

At the LFS, the "expert" told me not to get anemones because all anemones grow huge and move around and sting the coral. Is that accurate? Are there some options with anemones? They sure look nice.

Isn't a high rate of water flow important for a reef tank? Does reef safe have anything to do with the amount of water flow a species can tolerate?

To what extent are WCs important in a SW tank? Can you achieve a balanced ecosystem where SW WCs aren't needed? It seems like doing extensive SW WCs would be cost prohibitive. I just acquired a 125 gallon tank that I'm considering whether to use as a SW tank. I feel like doing weekly WCs on that would send me to the poor house quickly.

PWC`s are very important IMO. They take care of several things. They replace trace elements that are depleted through fish and invert processes. They help to naturally buffer your tank water. They also help to dillute excessive nutrients. I too have a 125 gallon tank and to me it`s not cost prohibitive. Yes I could add a bunch of chemicals but I prefer to do it the natural way and not a way that might crash my tank. That`s speaking from over 10 yrs of experience. IMO smaller frequent PWC`s are the key.

Answer yes they can grow huge and walk and sting other corals they also can get caught up in PH's and be sliced and diced , crashing your tank aswell

answer this depends on what corals you want some take high flow others take a lower flow

Ok. I guess I'm a little confused. One can dose a FW tank with trace elements. Wouldn't that work for a SW tank? Also, in a FW tank you have a balanced system with biofilters, and replaceable physical filtration media, etc to take care of the poo. Why wouldn't it be the same with a SW tank?

Most of your trace elements are found in salt such as your iodine calcium stronium (SP) mag and many more things as well that fresh does not use ... you can dose in SW but must test and really still may need to but water changes help to replace and dilute your fish poo.
With the removal of water change to remove disolved solids ect it should be done in fresh water as well

PWC`s are much more safer than added supplements. I`ve seen tanks crash from added chems but never seen one crash because of a PWC. It`s really not confusing.
