Frequently asked questions
Which Eheim Classic size do I need?
Eheim names the Classic range by the tank it suits: the Classic 250 (2213) handles tanks up to about 250 litres, the Classic 350 (2215) up to around 350. As always, match the model to your tank and round up rather than down — a canister run gently gives you cleaner water and more biological media.
Why are Eheim Classic filters primed manually?
The Classic range keeps a deliberately simple, sealed design with no self-prime button — you fill it once with a starter siphon or the accessory primer, then it runs almost silently for years. That simplicity is exactly why so many aquarists trust them: fewer parts means fewer things to fail.
Is the Eheim miniUP good for shrimp?
Yes — the miniUP is a tiny internal with a sponge intake, so it gives gentle biological filtration without sucking in shrimplets. It's ideal for nano and shrimp tanks up to around 30 litres, where a full canister would be overkill and too strong.
