If you're on a budget go with the classic. It already includes media and priming it isn't really that hard as some people make it out to be. If you want to spend more go with the pro 2. The 2026 should be more than enough for your tank.
More than enough but not too much? That's my main concern. If it's not an overkill I will probably get it despite the price... Let it be my b-day present
