i just bought my eheim 2075 1 day ago with a flow rating of 1250l per hour. however i went to try just now but im only getting a flow rate of about 620l per hour!!!! i only have the bucket inside with no media. i tested the flow rate by filling up an empty bottle and calculating the time taken to fill 1l. then multiply to get an avg rate per hour. can anyone help me. is the canister broken or??
