He was right they are differences a bog maxes bio where a reservoir max water held (plus your water in motion). I don't know why I did not understand that my brain was stuck in the bog guess.They’re typically different things. Bog is full of media to provide surface area for bio filtration. Reservoir is empty space for capturing as much water as possible.
Thanks! The one way valve has a spring loaded disc in it, it it pretty easy to push but it also is a fair bit narrower than the 2 inch hose where the valve is. If it's not ideal I wont use it. How necessary is it to have a one way valve in a pondless waterfall? Does it matter if the water comes back down the pipe if the pump is quite deep?That one way valve looks like it based off a ball or some thing blocking the flow back. This some thing must also slow to volume of water. I did not see how much it adds to the Total Dynamic Head.
4x4 is 2304 square inch or little over 1 psi. Cinder blocks here are 8x8x16 going with the bigger side that's 128sq in (not hole side up) times that by 5 is 640 by the 1 psi is no more then 640 pounds of rock and blocks at 38lb per cinder block.
Spray foam white black or tan all that I have used and I have used at least a dozen brands all seem to fade and loose their color.
The last thing I have to get is the structure for the reservoir. Aquablocks are pricey as here so I am thinking 2 plastic pallets, then some cinder block pillars, then 2 more plastic pallets. Could do all of that for like $40 or less. Thoughts?
- Expanding foam (standard) and some spray paint to hide it if needed (the black stuff is very pricey here)
- A bridge
- Loads of lava rock
I saw a youtube video of a boulder being craned on to a plastic pallet as a test and they seemed surprisingly strong!
Yes I've seen that too Have you heard of anyone using something like these steel cage pallets? Would turn it upside down and prob put a plastic one on top. I guess concern might be that soil shifting could start pushing the liner in but could put panels down the sides???I've seen a video of some yokel with a purple excavator setting a boulder on milk crates. Also surprisingly strong! Those were American crates though—cubic shape.
