I agree. My thinking is that a large island might make the pond “feel bigger” by obfuscating “how much further the pond might go”. I’m also thinking it will keep the kids more engaged by giving them something to “go around”. We will see if I regret that.

If 5 diffusers is the minimum, what would you do if it was your pond? I have time to plan all this out, so I want to get it right vs saving a few dollars on a few extra diffusers.

For the compressor, what depth would the 10 cfm be at? Any particular model you’re thinking of?
