I had a 2026 that I just sold. The thing rocked. Massive bio-filtration in the thing and could go months without being cleaned.
I haven't had any experience with 2028, but I think you will be happy with Eheim filters. I started out with 2215 and now I own 4 of them (3x 2217 and 1x 2215).Awesome! I'm going to look at it tomorrow. Hope its all in good order cause I would love to have one especially with how good everyone says they are!
It takes a lot of room inside the aquarium stand and very heavy to move for maintenance/cleaning.Give us some inputs on 2028 when you use it...
