That is nice on getting it for a few pennies off.
I am ion the fence. I need to get one that will fit my sump better. I have a 75g sump, which is 21 inches to the lip. The overall total inside height restriction is 39 inches.
SO... from the bottom of the outflow to the top of the lid needs to be between that range.
AND... suitable for a 400g tank system.
I have no problem raising it to fit, just have my head spinning from converting MM to inches. It would not be so hard except the american site of a German company has different documents that one will show English and the next metric. THEN... one had both, intermixed. UUgh... LOL
