Looking for some advice... I have a small 30 gal reef tank for the past year and just purchased a used 20 gal long sump box and a used reef octopus extreme 160 skimmer. I am going to set these up with my existing reef tank. What should be done to clean/sterilize this equipment before I hook...

I BOUGHT A BERLIN X2 WITH VENTURI PUMP, BUT I HAVE NO IDEA HOW TO SET IT UP PROPERLY. DOES ANYONE HAVE ANY SUGGESTIONS, HELP, OR PICTURES OF THERE OWN WOULD REALLY HELP. THANK YOU i have a 72 bowfront eshopps 125 wet/dry filter.
