Do I have a big enough filter?

I have an eheim 2236, rated for up to an 80 gallon tank/159 gph. Is this enough or should I look into upgrading? This is on my 46 gallon planted.

46 Bow Front Planted
Eheim 2217 & 2236, 2-39wt T5 bulbs (10,000), 72-75*
Pristella tetras, cardinal tetra, amano shirmp, bamboo shrimp, nerite snails, assassin snails and red cherry shrimp.

You might be pushing it a bit with the bioload looking at your stock. What kind of black tetra are you talking about? black widow, skirt or neon. You don't have any nipping issues with pristella and angel in the same tank?

Personally I would add another filter, with the media etc you have maybe x2-x2.5 volume turnover per hour.

I would aim for at least x4 total volume turnover per hour.

Would a Eheim 2213 be much better if I switched?

Other than a nervous feeling, is there something going on that indicates you need more filter? I would not let the opinions of others panic me into getting more equipment than my tank shows it needs. If the water is clear and tests good, that is about all my tank requires. I find Eheim knows quite a lot about what their filters will handle. Hobbyists like ourself often have opinions but rarely technical facts to back them.

I would stick with the 2236, the 2213 is smaller and only rated for a 66 gal max.

Agreed keep the 2236 and see how it fares my guess is it should be sufficient, I ran a 2236 on my heavily planted 55 for a year with no problems.

I am guessing it should be fine. Honestly, actual filtration isn't going to be a problem (likely). I have not had a big tank with a heavy bioload but I have had small tanks with a comparative high bioload and no filter and it's been one of my favorite tanks.


Flow, that may be another issue however. It really depends on the tank.
