發表內容: Hi, all:
I have been reading alot of posts in this site and other sites,too. I am puzzled about the lack of knowledges of the hobby among alot of people. I did not mean to insult anyone but actually try to help. I would like to tell you about what I think about the set up and maintaing of a reef tank. I will not get into too much scientific details but try to tell you all about what is a balancing ecosystem. One must understand what is a ecosystem first and that is how to create a balancing system. Each organisms and animals in the tank should served a purpose, not because the way they look. Corals, for example. There are corals that is very hard to be kept in the captivity and should not be purchased.Sun flower corals I find is very popular among asia countries requires daily feedings and almost no light at all is not one of my choice to keep. The carnation corals which requires phytoplankton and constantly stirring of the sand bed is another example. Fish wise, I find most of the hobbyist tend to keep them for the coloration rather than their functions in the tanks. I have never heard anyone mentioned about the sea cucumber in their tanks which is a great way to get rid off detritus and sand stirring method. Basically, What I am trying to tell you guys is that besides going to the fish store and try to find some exotic fish that have no purpose in your tank is not a way to create a balancing system. I will start by answering one of the most common questions asked on all sites, which is algae control in the reef tanks. Not only a nutrient free environment, but the combinations of different creatures in your tank is definitely the way to help controlling algae problems. It is now reveled that coral reef is not a nutrient free environment but actually in reverse. Corals actually need Nitrate to thrive, but we have been told for a long time that is not the case. Phosphate for example is lethal for coral`s calcification and there is no absolute ways to get rid of it. As long as you feed the tank, there will be phosphate. so what should we do? Like what I said before. By utilizing different creatures where one will assist another to maintain a healthy environment. In a reef tank, depend on the size of the tank,one should always have one or two algae eating fish, tangs for example is great. the best one is Chevron tang from Hawaii. Then snails. Turbo usually grows too large for an efficient algae control and Astrea snail should be utilized instead of turbo snails. Sepent staris a great scanvenger. Uneaten food, dead fish inside the rock, fish waste,etc. are all been taking care of. Hermit crabs, there are two types of hermit crabs that can efficiently remove green hair algae and red slim algae. They are blue legged hermit crabs and red scarlet hermit crabs. First one is the most efficient way to remove green algae and diatom algae, the latter one is great to remove all and red slim algae. Blue legged hremit crabs can also help stirred sand bed, too. Finally, the efficiency of sea cucumber is great to stirred sand but never noticed by hobbyist. They will eat the sand, take out the detritus and released the sand back. The cucumber`s digestive system can also given minor calcium to the tank when the sand is released back into the tank. By combining these organisms, one can create a balancing system and not to seek the assistants of artificial medium or chemicals. I am just rying to help and not to insult anyone, I hope you can all kind of think about the living organisms in your tank, what can it do for you?
