You really don't need all of the expensive equipment if your money is funny, All you need is a power head for good current, a hang on the back filter, and a protein skimmer and you're good to go. I've read on different forums that these people go and buy all of this fancy equipment and end up spending 700 to a 1000 dollars, for what? I have a 55 gal
saltwater aquarium all I use are 2 penguin bio filters, one is made for 75 gal
.the other is for 150 gallons, a protein skimmer, and a powerhead.I also use water conditioners and supplements with no problems.
