What would you recommend: separate reactor for each; combined reactor; or no reactor? I have a 55g reef tank. Right now I'm using a protein skimmer, a hang on water filter and doing 10g water changes every week 1/2. I'm looking to start bringing "more technology" into my tank to help out with my maintainace. Hopefully I will get my fuge up and running in the next couple of weeks. What else will I need that I should start working into my budget? Any input and comments will be greatly appreciated.
