The receptacle (ie the wall outlet) that you plug your aquarium related equipment into should be a GFCI receptacle, the same that you find your kitchen and bathroom...ie anyplace near water. You know, the kind with the 2 buttons:

(Aside, if your kitchen/bathroom receptacles are not GFCI receptacles, they should be changed ASAP, it's a hazard and they are required by building/electrical/fire code)
Someone who knows what they are doing should install the receptacle. It's not complicated... but if you've never installed an outlet before, don't try now as this is one meant to save lives. If you can't find a licensed electrician, someone familiar with electrical work or at least basic construction almost definitely knows how to do it. If you live in an apartment, your super probably knows. But you know your friends better than I.
Please test it (with the test button or a plug in type GFCI tester - easily found in stores too) after it's installed.
You can find GFCI equipment strips/surge protectors as well, much like you linked, which would work as an alternative, though not as ideal, IMO. Just make sure that any surge protectors or power strips are NOT simply laying on the floor near your tank. Raise them up, hang them on the wall etc (I also put a cover over mine with wood or acrylic as a drip guard because I'm compulsive)
Household receptacles (and the circuits that feed them) are usually either 15 A or 20 A, excluding specialized ones dedicated for special items like electric stoves, AC's, etc. Unless you have a huge tank with some pretty major equipment, you are probably safe with a 15 A surge protector, or 2. You can tell for sure if you know which circuit breaker in the panel box controls that outlet...it will be marked 15 A or 20 A.
My tank is in my dining room. Normally you wouldn't have GFCI receptacles there as it's not near water and not code required. Before setting up my aquarium though, I swapped out the standard kind that were there for GFCI's, knowing that there would be water around given the aquarium. It saved my life a couple months ago. I was being careless and had a spare surge protector on the floor while doing a water change. I slipped with my hose and spilled a couple gallons of salt water on the floor. The water puddled around and up into the cheapo protector...and around both my feet as I was standing there and not paying 100% attention. The GFCI tripped off, killing power to the strip which was now soaked. If it hadn't, I would have likely gotten a nice jolt from current passing from the water logged strip to my feet...or worse, up one foot, across my torso, and down the other.
GFCI = your best friend.
