Let's take this one item at a time.
1.) RO water is Reverse Osmosis water. This water has been run through a series of filters to remove all chemicals, salts and contaminates. When using this water for your tanks you need to add salts, chemicals, and conditioners to get the water to the correct make up for your fish to survive and prosper.
2.)An inline heater is a heater that is installed inline with the tubes to, usually, a canister filter. They can also be used with a sump system. They are usually installed on the return side of the filter.
3.) A UV sterilizer, quite simply put, is a piece of equipment that utilizes ultra-violet light to sterilize the water. It, again, is usually placed on the return side of a filter system. It works by forcing water to run around an ultra-violet light bulb, which is usually around 5-7 watts. The ultra-violet light destroy any living organism which could adversely affect the health of your fish.
4.) Kelvins is a thermo-dynamic term that uses absolute zero as a starting point. Absolute zero is a theoretical term where a temperature is reached that a body neither radiates nor absorbs energy. A light bulb is sometimes rated in kelvins which denotes the operating temperature of a bulb. In theory, the higher the kelvins, the more closely the light emitted by the bulb resembles the natural light ofthe sun.
As for items 5 and 6, I am not real familiar with the use of either CO2 or with drip systems. CO2 is used in heavily planted tanks to promote healthy plant growth. I'm sure one of our plant gurus will reply here. Drip systems are most generally used in saltwater applications. Hopefully, one of our "salties" can answer that question better than I. Of course, you can always Google it.
