This catches people out because the 1050 and the 1620 share the same 16\/22 mm hose size, so the plumbing interchanges even though the media does not. Check the model code on the canister body.\u003c\/p\u003e\n\u003ch4\u003eHow much media does the 1620 L\/h canister hold?\u003c\/h4\u003e\n\u003cp\u003eBioscape lists a 9.0 litre filter media capacity plus a separate 0.8 litre pre-filter chamber, and rates the filter for aquariums up to 400 litres. The external dimensions are 260 x 260 x 450 mm and the hose size is 16\/22 mm.\u003c\/p\u003e\n\u003ch4\u003eDoes activated carbon remove medication from the tank?\u003c\/h4\u003e\n\u003cp\u003eYes, and it is the most common reason a treatment appears to fail. Carbon adsorbs most aquarium medications, frequently within hours of dosing. Remove the pack before starting a course, then fit a fresh one once the course is finished to clear the leftover residue.\u003c\/p\u003e\n\u003ch4\u003eCan I recharge or reuse the carbon pack?\u003c\/h4\u003e\n\u003cp\u003eNo. Baking, boiling or rinsing spent aquarium carbon does not restore its adsorption capacity. Once the sites are occupied they stay occupied, and the pack should be replaced.\u003c\/p\u003e\n\u003ch4\u003eDo I need to run carbon in the canister all the time?\u003c\/h4\u003e\n\u003cp\u003eNo, it is optional. Many keepers run carbon only when there is a specific job for it — clearing tannins from new driftwood, removing medication after a course, or lifting a yellow cast out of an established tank.
