Growing eelgrass as my first seagrass

[Urchin boy]

So yesterday I decided I really want to grow seagrass of some sort by adding it to my deep sand bed of about 10-12 centimeters and I realised there is a species available where I live called zoostera Marina aka eelgrass and I managed to collect 2 of them from my local beach not far away from where I live and I now have them planted in my so far empty tank although I can't yet see them because my tank is still cloudy from the sand I added but once it clears I should be able to get a first look.

I do know about CO2 dosing being used to grow seagrass that and the special tablets one can use to make them grow better.

Has anyone else here tried to grow them?

I set my temperature to 23 degrees Celsius as it is more of a cold water species which is not as big of a deal as I am not really interested in corals mainly focusing on the invertebrates.

Haven't grown them but have been around them in the sea a bunch, so I looked it up. They do better in lower temperature and lower salinity.

Maybe look up the conditions of the place you actually get yours from.

This paper suggests they do best at 10-20°C and 15ppt salinity rather than 35, but they can still live at 35. But there might be different subtypes adapted to different habitats.

I will adjust the temperature then as for my salinity I will have to lower the salinity from about 30 ppt to 15 ppt ,also what fish species would be best suited for this?

Some gobies and pipefish, maybe some shrimp would make for a nice biotope tank.

Be careful though, if you get cold water fish you might need expensive active cooling in the summer. And especially with pipefish, feeding them is a concern.

Put a bunch of research into whether all the things you want to keep do well with the salinity and temperature the tank is going to have summer and winter

I am from Sweden which usually has only mild summers and very cold winters and it is possible I might keep only invertebrates like sand dollars and snails that I feed regularly

For my deep sandbed I am definitely considering nasarius snails as they would be quite useful to help stir the sandbed
