Ive been raising freshwater fish for many years and I now think Im ready to enter into saltwater, except it seems VERY daunting, any info pertaining would be greatly appreciated. I want to use a spare 29g tank for my first saltwater setup. Ive read over many FAQs on saltwater and it is very confusing. Exactly what equipment do I need powerhead, protien skimmer, ect. and what kind of fish would be good for a 29g?
