Freshwater Phytoplankton in a reef tank?

[vdubers]

Hi all bit of a strange one but I couldn't find any previous posts. Would freshwater phytoplankton still be a beneficial addition to a reef tank? And if so any reason not to culture outside?

I have a spare glass aquarium left outside before moving to storage after breaking down a cherry shrimp tank, this filled with rain water and even with the limited sun during the winter here in the UK it is now full of "green water" which I am assuming is phytoplankton. I have added nothing to this outside tank but it likely has nitrate and phosphate left from the shrimp tank.

Would this freshwater phyto be beneficial to a reef tank even if would just die right away when it enters salt water? Would it even die right away?

While I do have a small marine phyto culture inside just leaving a glass tank outside and getting usable phyto seems much easier and larger volumes.

Thanks and apologies if its a ridiculous idea.

Personally I would not add it to my tank. You assume its phyto just because its green, but sounds like it is just a box of stagnant green water left outdoors for unknown amount of time. Who knows what crawled in there?

I think at the best you would just dirty your water. Osmotic pressure would cause cell issues anything living would die.

Thank you for the replies. Sounds like potentially a bad idea. Worth asking though maybe I will try some sort of semi sealed unit and try marine phyto outside.
