hey everyone the water in my tank is reallly merky right now and i can barely see the other side

i just added my second eheim pro II 2028 today. i was wondering how everyone is keeping their tank water crystal clear... thanks
Every filter, I think has a place and specific purpose. Eheims are excellent and second to none, as far as biological filtration goes. They however, *can not* be used as the only source of your mechanical filtration, specifically when it comes to large, waste producing fish.
What sort of mechanical filtration do you have? I have always had huge success in keeping water very clear, by using aquaclear mechanical filters, and adding poly-fil in it as means of polishing the water. The ACs are also relatively easier to clean, compared to eheims, on a weekly basis.
I would therefore recommend, if you haven't done already, to have a AC set up for the tank (i.e., if you do have some funds for the filtration, since you've added two eheim pros

), or maybe two -- depending on how large the tank is.
Another solution is FX5. I am currently using it as mech-only filter for my 125, while the bio filtration is done using an eheim 2260. FX5 is an excellent choice if you are picky about the noise filters make -- ACs would definitely be noisier compared to FX5.
Hope that helps!
