Running some GFO
until you can get your water straightened out may be a great idea. I run it when I'm on vacation just because I know the person feeding is going to overdo it! I still think that you have too many fish. I run carbon in my tank and always have HOWEVER, recent studies have shown that running heavy active carbon in saltwater aquariums can cause "Head and Lateral Line Erosion" if you don't supplement the water by adding trace minerals. If you have tangs (surgeonfish) it's not necessarily a great idea unless you choose to use trace mineral additives!
A lot of people with freshwater tanks run it because it takes away that "yellow tint" that water can get. It also removes some large organic molecules, medications, chlorine, pollutants and toxins, as well as other types of chemical elements that a protein skimmer or another means of filtration may not remove. Basically, it's not needed but I use it and add trace minerals.
As far as the comment regarding the tang...+1
Tangs need a lot of room and space...a rediculous amount it seems when coming from freshwater to salt. Basically, when it comes to the number of fish you can have, and the type, all the rules change for saltwater. That little bitty juvenile tang that's only about 2 inches needs about 40 gallons to swim in to be healthy. They are very active fish, extremely sensitive to EVERYTHING, and BIGTIME grazers. You need to supplement his diet with algae sheets etc. If you don't, he will eventually die. Honestly, they usually do not do well in tanks that are not decently established. I find it irritating that sites will claim them as "easy" level of care. They are so picky and susceptible to disease. They usually will live for a few months in a new tank and then die. If anyone knows of someone that has a FOWLR
less than 90 gallons that introduced a regal tang after the cycle and has it 6 months later, I would be interested in knowing what they did! I've never put one in a small and new tank.
Hmmm...I will stop now! LOL! I just wrote a dissertation and apologize! Let us know if you have any question! We may not always know the answers but most of us can and will help you find them!
