Adding bog filter to existing pond

[Jutt]

Hoping to get some rough input to the above ground bog filter i'm going to be adding to my existing pond.
So at the moment i have a roughly 600 gallon pond and i bought a 100 gallon stock tank. https://www.tractorsupply.com/tsc/product/rubbermaid-structural-foam-stock-tanks-100-gal-capacity
As you can see the tank already comes with a 1.5" cleanout,, so would i connect the pvc im using to this existing cleanout?
The pond pump i'll be using is a tetra 1900GPM.
The bottom of the stock tank , the PVC pipe will be laid out in such a way that its evenly distributed then come up and over the top of the tank so the filter hose can attach.
Am i right im assuming that 1.5" pvc would be large enough / too big?

Myself i would order one aquablock, or any matrix block i can find. i would use the clean out on the bottom as the feed for the bog but before i connect i would put two ball valves on just before the pipe enters. one will feed the bog the other will be to drain.
at the bottom i would then build up just higher than the intake feed with some brick columns. place the aquablock PANELS on these columns so your creating a plenum at the bottom of the bog , cover the entire bottom of the bog or as much as one block will cover and then place 2-3 inch river rock around and over the panels . then add your 3/4 river rock now i am not a fan of going down to 3/8 peastone i feel its too fine and can cause premature blockage. Others will disagree but thats my opinion. as far as how to get the waterfall that is more of a challenge to me i would go with three 3" uniseal / why three because plants can block these easily if your away or just not doing daily inspections. but then i would create a weir to hide the pipes not my cup of tea but it will stay water tight . This will not require a clean out pipe as the ball valve at the bottom will do that open the valved and let it drain down.

The Aquablox panels ,you mean these ? >

And could i just utilize that ledge in the tank also for them, ( it is above the intake )
and with using your described method, id be not using the pvc pipe at all ,or would i still need to attach a PVC pipe on the inside of that intake ?

yes but if you get the small blocks they only have 8inch sides you'll need more than one you have to put enough supports in to hold all the gravel spanning from one side to the other is too far the gravel will break the panel . if you span similar to a put together block you'll be fine. youll probably need a couple blocks one 18 inch large block may be enough by its self

Just want to apologize up front for any stupid questions that come next...
The aquablox in the tank, that would be a complete blox, not the panels laying "flat" ?..(kinda like in the picture ?)

if that is correct ,is there any reason why i couldn't use what i have there now ?
The next photo is how it would be set up regarding the ball valves at the inlet ?

if i use the inlet fitting that came with the tank the only way to attach the pvc would by means of a trap adapter which by the looks of it reduces from 1.5" to 1.25",would that reduce flow?

View attachment 167428there are no dumb , you got the idea with

H creating a plenem correct milk crates can do the job. If you have to cut them you could use plastic and stainless steel zip ties to make the crates strong again after you cut them and reinstall sides in a new location on the milk crate.. or just do one row down the middle then install like 8 to 12 inch rocks up to the top of the milk crates where you shift to smaller 3 inch and so on but they all need to be river rock smooth and round,

if that is correct ,is there any reason why i couldn't use what i have there now ?

View attachment 167429you got the right idea. Milk crates would do the job as well, there is no right or wrong just concepts that work better than others you got through t

Theclean out is right you want the plumbing to flow out the ball valve and not have to reverse flow.that is what i was refering to your good or i have gotten better describing,

if i use the inlet fitting that came with the tank the only way to attach the pvc would by means of a trap adapter which by the looks of it reduces from 1.5" to 1.25",would that reduce flow? .............Yes but if I remember you were a pond of 500 GAllons and your flow should be fine if I had to guess 1 1/4 is probably good for around 2800 gph. In pvc I would not push more than 1200 gph through a bog that size but that's me.

Long..?
