Not all corals are photosynthetic. These non-photosynthetic species need regular feedings in order to survive, and unless you adapt to care for them they are best left in the ocean.
Metal Halides and T5's are both great lighting techniques there is not a clear winner between the two. IMO it is personal preference between each reefer.
You can keep a reef tank without a skimmer. But it's one of the best pieces of equipement you can buy for your tank. It helps to remove waste build up.
There is a relationship that is sometimes overlooked in acclimation between NH3 and NH4. When corals are shipped and organic matter (sponges, detritus, etc) starts to rot, ammonia levels increase and pH decreases (causing more free H+ ions in water). When a coral is acclimated to a normal system with a higher pH, these free floating H+ ions rapidly connect with NH3 and create NH4, which is a much more dangerous form. In fact an increase of one pH unit will increase the NH4 concentration about 10-fold! Some professional systems will acclimate new arrivals with low pH water until the NH3 levels are removed, and then switch over to system water
Not all saltwater aquarium fish are "reef safe." Be sure to do your research before getting a salwater fish, or you might loose a lot of nice corals.
:nerd:
Plan ahead and research what you REALLY REALLY REALLY want in your tank rather then buying all the things that catches your eyes.
It sould be your hobby not your credit card debt that last till year 2025.:cry:
1. the less I mess with my tank the better off it is.
2. egg crate sux.
3. keeping a reef is more about keeping water than it is about keeping fish and corals.... stability,stability,stability
