Good for you on your first build! You did more than most of us! Thank goodness for UA-cam where you can learn almost anything! Thank you for sharing your project!
I have a plan to build a 4.5m x 2m raised bed (outer) with 7N 140mm solid concrete blocks (27kg) height will be 4 courses high (225mm x 4) from just below ground level Do you think those blocks would be strong enough laid in the 140mm wide configuration? to support an incorporated small pond at one end, probably have it as a 3 course high with coping stones. Only perhaps 600mm x 2000mm for a water feature with some small fish in it. I think it'd be plenty strong enough but looking around the internet I see some folks building seriously beefy walls and started having doubts.
I've done some converting to do the Math. I'd be worried about a couple things , it's not very deep so the sun is going to turn the water green rather quickly. The sheer volume of water may be too much for those bricks. That's a lot of water pressure up against those bricks. Even my bricks are filled with concrete. If my conversion is correct it's 15 ft x 6½ ft and 3ft tall
@@justanotherguppyguy Thanks for replying - the largest part of the bed will 4 courses high and have soil backfill for veg planting etc. I have some stainless wall ties I intend laying in the mortar bed between courses as a little extra strengthening. The pond part of the same bed (compartment if you will) is only going to be a smaller step down 3 course high section at one end with coping stones and estimate that to be 6ft x 2 ft and about 3 ft deep (when I dig out a little below ground level.) fyi I'm not wanting to house showroom Koi just a few gold fish tiddlers and a few aquatic plants with a little airating waterfall or fountain of some sort.

Good job!
Nice!
Im gonna build one myself to keep myself cool on extreme hot day.. NICE JOB BROTHER👍👍
i think u need also a bottom drain for your comfortable water change.
Aim rania moracan iy love you joobbb good job

Did you fill the inside holes of the cinderblocks with concrete?
Yes I did
Did you fill the block with concrete for strength?
Yes
Rebar?
How many bricks did you use
And what's the capacity
I only remember it was a pallet and a half. It's a little over 1000 gallons
Any structural issues
Nope. It's been a couple years now with no problems
