So I've been thinking about changing my substrate for the last week, especially since getting my loaches. Although I have a smooth, fine gravel what suits them would be best.
But I also like my gravel. Which has led me to a new idea.
I'm wondering about creating a kind of beach effect, in that I'd have maybe 1/3 of the tank as sand substrate which would form a shallow incline into my gravel, as this is kind of what the pebble beaches look like in my area.
So I'm wondering how this would be possible, or even if. I know sand typically is around 2 cm deep in most tanks whereas gravel is approx 5 cm. Mine is anyway as per what I read. Would deeper sand make any diff? Shallower gravel?
I know a lot of bacteria etc lives in your gravel, but I honestly have no idea if this works the same with sand, or what the differences here are.
This definitely isn't an idea set in stone but certainly something I've thought about to create a different look.
