Little Mussels are n saltwater tank

[kfkirien]

Hi, I started to cycle my 280G tank with salted RO water plus 10% seawater. Some live rocks with macroalgae were brought in from the coast and already introduced into the tank, see pictures please.
It's already 10 days and ammonia is high 8 ppm. I'm still waiting for the bacteria blooms. The macroalgae works fine but the interesting thing is that there are a lot of small mussels hanging on the algae since few days now.
My concern is, is it healthy to keep young mussels and raise them in tank and not have an impact on ecosystems in the future?

Mussels, oysters and clams are all considered beneficial filter feeders but they are quite uncommon in a reef tank due to the cooler temperature requirements they have.

Some species live in warmer water and those are the species you will want for longterm stability.

Thanks Saltreef for your response.
The fact that I have no fishes in the tank nor corals because I am still on my way to fulfilling the nitrogen cycle. The temperature was raised to 27 °C to help the nitrifying bacteria bloom.
I'm planning on getting a marine tank of clowns and plants.

As mentioned, the mussels are harmless filter feeders (and cool hitchhikers which would be cool to have survive) - honestly, at this point, I'd be more concerned that the 8 ammonia would kill them then I would be of them causing problems in your tank (a reading of 7.6 is the LC50 for the Asian Green Mussel, Perna viridis).

If you want to try and help them survive and grow, then (assuming they survive long enough for your ammonia levels to fall) you can try offering them some Isochrysis galbana (T-Iso), Chaetoceros sp., and/or Thalassiosira sp. phytoplankton.

Yes, you are right about ammonia levels.
I did a 10% water change only a few hours ago and plan to do another 20% seawater change by Monday to lower the ammonia level and increase the nitrifying bacteria naturally.
As long as the mussels are not harming the ecosystems nor the inhabitants, I would definitely put more effort into keeping them safe in the tank.
