yes , but mine looks older the foam and charcoal are one unit,

Okay this one runs at 185 gallons per hour or 700 liters per hour.

Now what is your gallons for your tank?

tank is 30 gallons

that one says max 34 gallons, should i go up to fluval 4plus?

Your tank is cycleing at 6 times an hour. We always suggest with goldfish since they are so messy, 10 times an hour....the #4 would only give you a 8 times an hour that would get you by but I might go if you can an Hang on the back filter of about 300 GPH.

which one do you suggest? I'am in Canada, is the aqua clear one good?

Aqua Clear is a great inexpensive filter......Allot of people here use it

aqua clear is a great choice
