Yup filled to the top.... I did a water change and didn't shut the filter off and that is why i did the video to show people the output power...
There are a total of 12 holes now 6 on the front and 6 directly across thru the back...
There were originally 6--- 1/8" holes but this proved to be too small as the water shot across the tank to the other side... I drilled up to 15/64" and still had strong streams of water shooting across the tank... I was going to make another spray bar so i drilled thru with the 15/64" bit and that really calmed things down to a more acceptable level...
12 holes @ 15/64 is good now i need to redo the spray bar to help push the detritus towards the other side instead of gathering in the middle... I vacuum the detritus every other day so it's not on the "priority list"...
I think it's a great match... for the 40... I was afraid it was going to be too strong... It actually was going to go on a 55 and i wanted to cycle the filter first since the 55 stand was another project.
I wouldn't trade my Eheims for anything..
I would do it again in a heartbeat... infact i am going to pick up another 2217 and just load it with substrat pro when $$ becomes available hooked up to a turbo twist 18W for my EBJD project hopefully to happen by the end of the summer..
I didn't want people to also think i was being baised i own both...
