substrate for seagrass

[andycook]

I am planning a sea grass tank (shoal and turtle). This will be a new tank. I am considering a layer of soil on the bottom, then a laterite layer, and then a mix of sand/crushed coral. Anything wrong with that? Anything better?

I've had luck with turtle grass in the past but that was with an established and gunky 8" DSB. This is a new tank.

Gunky sand is the best. Failing that, maybe mix a bit of soil into the sand.

I use aragonite mixed with ecocomplete and Seachem onyx sand. I also use seachem flourish tabs.

Tagging along... Would there be any benefit to using dry sand that used to be gunky?

Be sort of like potting soil for seagrass

That's what I was thinking. Thanks for the reply!

I would rinse it first.If you have too high organics/gunkyness in the mix it will go anoxic and produce H2S killing the grass.

Note taken. It seems it would be a tricky balance having enough nutrients but not too much. In my mixed reef, I just try to keep lowish nutrients....you know all tests 0.
