Your doing great! That filter is the biggest filter I have ever layed eyes on. That is what I would like to see a lot of pics of, how it works and what has to be done to maintain the thing, how long it would take to clean and what all is going in, and how often do you have to clean, or if it is self cleaning
,also how the pond works, from the bottom drain all the way to the filter and bakke shower system. Would you flip a switch and flush the filter or do you do this by hand.
If you have to take everything out of that filter it could be a all day job.
