Hello, aquarium enthusiasts!
I live in Washington DC and have a 25 million liter short rimless fish tank which I’d like to stock with plants and animals. Annoyingly, it’s only about 45cm deep at the shallow ends, so I’m not sure what would work best.
It’s also outdoors, and obviously a bit too large to move. Please help! The algae is going NUTS, so I’d like to prevent that. Plecos? Saltwater? Idk, this kind of isn’t my field of expertise and my cabinet is really busy with this whole “Texas secessionist movement” bullshit.


45cm is not very deep for a fish tank. You should make your fish tank a lot deeper.
If you want to say your fish tank is more splendid than the ones at doctors’ offices, you’re at least going to have to make it 120 cm deep.
It’s about 75cm deep in the middle, does this help?
Also I can’t make it deeper because it’s in the ground, so I guess it’s more of a fish pond than a fish tank?
Bring out your bulldozers and get to work.
You don’t want people to have a reason to say your fish tank is “dimensionally challenged”, do you?
It’s also a “historic monument” or some bullshit so the mayor won’t let me do jack shit.
