Read the specification in context
Record the baseline and check the stated 227–416 L range. Do not infer the aquarium's condition from a single sign. Identify the variant, market, document date and which claims come from the manufacturer.
Then compare the largest AC body and high nominal circulation with livestock needs and recent changes. Translate nominal figures into space, flow, access, energy and maintenance requirements.
Check fit and limitations
Adjust one variable and assess hanging weight, level, clearance and return distribution before continuing. Keep a reference so the result can be compared. Confirm availability, spares and exact package contents before using the profile to buy.
Do not mount it on an incompatible rim or assume the waterfall sweeps the entire bottom.
