Welcome to AA
How are you
cycling the tank? First off if “money isn't a factor” then you might want to highly consider having a local professional both set it up and maintain the reef tank for you on a monthly basis. Especially if keeping it as a “show tank” in an office environment. I’ve seen too many “show tanks” that look terrible because the office didn’t have the necessary experience to run a reef tank.
The Penguin 350 bio-wheel is better suited for FO systems and not for reef systems since they trap waste and kick up your no3 levels which you want to keep at or below 5 ppm in a reef tank.
Using about 70-90 lbs of base/live rock in the tank is best for a reef environment and will provide all the
biological filtration needed along with proper water movement and a good protein skimmer.
For starters on what you need
read this post to get familiar with the equipment/terms of keeping a SW tank.
If not getting a sump then I’d get the
AquaC Remora Pro skimmer which is one of the best HOB skimmers.
A skimmer removes waste from the tank before it can convert to nitrate.
Your lighting will need to be upgraded if wanting corals since you only have basic florescent lighting currently. The wattage/type of lighting will be dependent on the type of corals you want. If wanting
medium light corals the VHO/PC lighting in the 192-250 watt rage would be fine. If wanting
high light corals then MH/PC would be needed in the 300+ wattage.
Current USA &
Coralife Aqualight are two very popular units.
For fish 3-5 small fish (2”-3”) or 2 larger (4”-6”) and one smaller fish is about the max you want to stock your tank with. I would go with smaller fish personally which are more enjoyable IMO and are less messy.
liveaquaria.com has a section devoted to smaller marine fish.
Research is key to a successful SW tank and I’d highly recommend reading all the
saltwater articles on this site, the
articles on liveaquaria.com, & picking up a
good book. All are excellent ways to get acquainted with all that’s required for this expensive hobby.
